The present textbook deals with exactly solved models and their diverse applications in several branches of physics such as mathematical physics, statistical physics, condensed matter physics and so on. Exactly soluble models are currently considered as an inspiring research field in its own right, which regrettably requires a considerable knowledge of sophisticated mathematics. Accordingly, my primary ambition was to provide an intro- ductory course for undergraduate students that would cover the simplest exactly solved models, whose rigorous solutions are available even after modest calculation. The present textbook should be therefore regarded as an auxiliary graduate-level textbook, which should serve as the student’s guide on this beautiful but surely intricate subject.

Even although I attempted to write largely self-contained textbook for undergraduate students, it is worthy of notice that the course on Exactly Solvable Models in Statistical Physics demands essential knowledges from the quantum mechanics, statistical physics, phase transitions and critical phenomena, which are its indispensable prerequisities. The most crucial fundamentals of these theories are briefly recalled in introductory remarks just for remembering and not for substituting those comprehensive courses. The rest of this textbook is entirely devoted to exactly solved lattice-statistical models with the main emphasis laid on their possible applications in the condensed matter physics. It is the author’s hope that the presented exact solutions are detailed enough in order to be easily followed by undergraduate students even without a support of tedious proofs, cumbersome theorems, longer argumentations, or obvious facts. This rather necessary compromise has of course a certain unadvisable impact on ’exactness’ of the presented solutions.

Finally, it is worthwhile to remark that the present textbook makes just a slight introduction into the simplest exactly solvable models and thus, the interested reader is referred for the follow-up study to several excellent books on exactly solved models quoted in the bibliography list on the next page. Note that the listed books were the major knowledge sources used by creating this textbook and they might be regarded as more advanced literature on this exciting research field.

The structure of the animal body is extremely varied. Each species has its distinctive morphological features, which bears as a testimony to long-term development and belonging to the developmental lineage. At the same time, the body has been tested for a long time by natural conditions, resulting in unique adaptations to the environment and life strategy. Despite this admirable variety - which includes both recent and fossil animals and which we have far from mapped – a comparison of body parts brings knowledge we can generalize: the main building principles, and boundaries within which phenotypic diversity is realized. Comparative animal morphology today uses the latest methodological material and knowledge from other disciplines, from genetics, molecular biology and experimental embryology, through progressive imaging methods (e.g. electron microscopy, computer micro-tomography) and the possibilities of subsequent software processing of image material (measurement, staining, etc.) to the view of physics, chemistry, statics and geometry on the structures (to nanostructures) of the living body. Detailed knowledge of historical and contemporary conditions on Earth is an important interpretative context in the study of animal morphology. Surprisingly, the knowledge accumulated after centuries of research is now rapidly supplemented by new knowledge, and often the traditional knowledge is subsequently reinterpreted. Finally, and no less important, in studying animal (and human) morphology, we learn surprising knowledge about ourselves. The author of the presented textbook had the ambition in a simplified form to introduce the reader, especially the student of biological studies, into a dynamic and fascinating scientific discipline, as the current comparative animal morphology is.

The publication is focused on discrete random processes, primarily on Markov chains, which have wide application in the field of economics and finance.

The textbook is divided into five chapters, the first of which serves as an introduction to random processes and provides definition, properties and classification of random processes in general. The second chapter discusses Markov chains with discrete time, including valuation of transitions between states and their optimal management. The third chapter focuses on special Markov chains with continuous time and emphasizes construction and solution to the system of Kolmogorov differential equations, which describe the dynamics of the process development. The last two chapters illustrate applications of Markov chains using examples of queuing system modeling and renewal theory.

Besides the explanation of basic terms, definitions and theorems with proofs, this textbook also provides number of solved examples to illustrate the discussed theory. Problem assignments are placed at the end of each chapter, so that readers can test their understanding of the content as they progress through the book. Solutions to all the problems and the list of references are provided at the end of the publication.

This textbook is primarily intented for students majoring in Economics and Financial Mathematics at the Faculty of Science of Pavol Jozef Šafárik University in Košice, and it covers content of the course “Random Proceses 1“ thought there. It might however serve also students from other schools in similar progams or professionals interested in this topic.

Súčasná výučba chémie má svoje špecifické problémy. Na jednej strane sa v dôsledku posunutia ťažiska učiva chémie v prospech učiva teoretického, zvýšila náročnosť učiva chémie a v súvislosti s tým, sa znížil záujem žiakov o chémiu. Nezáujem žiakov o chémiu je najviac podporovaný názorom, že je to práve chémia, ktorá výrazne prispieva k zhoršovaniu kvality životného prostredia. Na druhej strane žijeme v dobe, keď sa s produktami chémie stretávame prakticky všade. Nutné je spoznať základy chémie čo najlepšie, preto je otázka zvýšenia záujmu o výučbu chémie a zvýšenia jej účinnosti veľmi aktuálna.
Do slovenských škôl vstúpili štátne vzdelávacie programy ako základ pre tvorbu školských vzdelávacích programov. Tu je kladený dôraz nielen na získavanie určitej sumy znalostí, ale na vytváranie a rozvíjanie kľúčových a špecifických kompetencií žiakov, na ich prípravu pre celoživotné vzdelávanie a uplatnenie sa v živote. Preto je stále väčšia pozornosť venovaná jednému zo základných didaktických prostriedkov pre zvýšenie aktivity žiakov vo výučbe, a tým aj zvýšenie efektívnosti výučby chémie – učebným úlohám.
Z teórie aj z praxe výučby chémie vieme, že učebné úlohy, otázky, príklady, cvičenia atď., sú jednými z dôležitých súčastí každej vyučovacej hodiny. Učebné úlohy sa uplatňujú vo všetkých fázach výučby – vo fáze motivačnej, vo fáze osvojovania učiva, vo fáze upevňovania učiva a vo fáze kontroly osvojeného učiva. Je teda zrejmé, že každý učiteľ sa ocitne skôr či neskôr v situácii, keď bude musieť učebné úlohy vyberať z učebníc, pracovných zošitov, zbierok a príkladov, alebo ich tvoriť sám.
Vedecká monografia je určená pedagogickým odborníkom i učiteľom chémie, ktorá ich má zoznámiť s ukážkami rôznych typov a foriem učebných úloh a so základmi ich tvorby v chémii a môže byť pre nich nápomocná pri tvorbe atestačných prác zameraných na tvorbu testov a ich štatistické vyhodnotenie.

Over the past fifteen years, the course on ’Exactly Solvable Models in Statistical Physics’ has become an indispensable ground of the study programme ’Theoretical Physics’ at Faculty of Science of Pavol Jozef ˇSaf´arik University in Koˇsice. At first, the course based on the first edition of this textbook was intended for undergraduate students only, however, I have later prepared follow-up course taught at a postgraduate level on demand of several ambitious students who wished to continue in studying this exciting research field. It is already more than decade when our students enrolled in the study programme ’Theoretical Physics’ graduate from ’Introduction to Exactly Solvable Models in Statistical Physics’ at a master level and ’Exactly Solvable Models in Statistical Physics’ at a postgraduate level. Of course, it was necessary somehow to rearrange topics for the courses of undergraduate and postgraduate students. More specifically, a few more challenging topics concerned with exact solutions of 2D Ising model (chapter 3) were moved to a more advanced course intended for the postgraduate students, while an introductory course intended for the undergraduate students was contrarily supplemented with a few new topics requiring the second edition of this textbook. The second edition of this textbook thus contains a completely new chapter 4 devoted to the exact solution of the Ising model on the Bethe lattice using the method of exact recursion relations, while the chapter 5 was supplemented by exact results for ground state of a few frustrated Heisenberg spin models using the variational method. It is my hope that the next edition of this textbook will come soon and it will involve all topics specifically taught within the postgraduate course as well.

This is a supporting text for the undergraduate students interested in quan- tum theory of magnetism. The text represents an introduction to various theoretical approaches used in this eld. It is an open material, in the sense that it will be supported by appropriate problems to be solved by student at seminars and also as a homework.

The text consists of four chapters that form closed themes of the in- troductory quantum theory of magnetism. In the rst part we explain the quantum origin of the magnetism illustrating the appearance of the ex- change interaction for the case of hydrogen molecule. The second chapter is devoted to the application of the Bogolyubov inequality to the Heisenberg model and it represents the part which is usually missing in the textbooks of magnetism. The third chapter deals with the standard spin wave-theory including the Bloch and Holstein-Primakoff a approach. Finally, we discuss the application of the Jordan-Wigner transformation to one-dimensional spin-1/2 XY model.

The primary ambition of this supportive text is to explain diverse math- ematical methods and their applications in the quantum theory of mag- netism. The text is written in the form which should be sufficient to de- velop the skills of the students up to the very high level. In fact, it is expected that students following this course will able to make their own original applications of the methods presented in this book.

The reading and understanding this text requires relevant knowledges from the mathematics, quantum and statistical mechanics, and also from the theory of phase transitions. It is also expected that students are familiar with computational physics, programming and numerical mathematics that are necessary to solve the problems that will be included in the MOODLE educational environment of the P.J. Safarik University in Kosice.

Finally one should note that the text is mathematically and physically rather advanced and its understanding assumes supplementary study of the books listed in the list of references.

Zborník abstraktov Študentskej vedeckej konferencie PF UPJŠ

Charakteristickou črtou vzdelávania na kvalitných vysokých školách, ku ktorým Prírodovedecká fakulta UPJŠ v Košiciach patrí, je úzke prepojenie vzdelávania a vedeckého výskumu. Poznatky a vedomosti z odboru štúdia získavajú študenti nielen teoretickým štúdiom jednotlivých disciplín, ale aj aktívnym zapojením sa do riešenia čiastkových vedeckých úloh v rámci výskumných tímov či už pri vypracovávaní záverečných prác alebo formou nástroja Študentských pomocných vedeckých síl (ŠPVS), ktorých činnosť sa na fakulte revitalizovala v roku 2015.

Študentská vedecká konferencia (ŠVK) je jedným z tradičných podujatí fakulty, ktoré je organizované počas Prírodovedeckých dní ako súčasť Sciencefestu. Svojou povahou prirodzene zapadá do spomínaného súkolia prepojenia vzdelávania a vedy a dlhodobo sa teší veľkej popularite a záujmu študentov. V roku 2016 na ŠVK vystúpilo 125 študentov Prírodovedeckej fakulty UPJŠ v Košiciach, v rámci 16 sekcií. Prehľad o zameraní a cieľoch študentských prác podáva tento zborník. Veríme, že bude inšpiráciou pre ďalších potenciálnych záujemcov o vystúpenie na ŠVK, ale bude zaujímavý aj pre širšiu verejnosť, ktorej môže podať doplnkový pohľad na činnosť fakulty.
