Elementy matematyki dyskretnej
Jolanta Pozorska, Izabela Zamorska
Matematyka dyskretna jest fascynującym działem matematyki, zlepkiem innych działów, ewoluującym od wieków. Interesowali się nią już starożytni, lecz największy rozwój matematyki dyskretnej przypada na wiek XX n.e. Cały czas się rozwija i wymaga ciągłej aktualizacji wiedzy, przez to wciąż można na nowo ją odkrywać. Znamy już sporo jej zastosowań, a ile jest jeszcze nieodkrytych? Wciąż wiele pytań zostaje otwartych, wiele twierdzeń i lematów nieudowodnionych. Podręcznik Elementy matematyki dyskretnej przeznaczony jest nie tylko dla studentów kierunku informatyka, ale również dla wszystkich pasjonatów matematyki dyskretnej. Każdy znajdzie w nim coś interesującego dla siebie. Wybór zagadnień jest subiektywny, dlatego zapewne omawiane tematy nie zostały przedstawione w sposób wyczerpujący, jednak wystarczający.
First Order Ordinary Differential Equations. Course book
Anita Ciekot, Izabela Zamorska
This book is designed to introduce readers to the fundamental concepts, techniques, and applications of differential equations, providing a solid foundation for further study or practical problem-solving. It is specifically intended for students of technical universities. The textbook is divided into five main chapters. In the first chapter, we will explore basic concepts and notation, establishing the language and framework necessary for understanding differential equations. Definitions and essential terminology will be clarified, accompanied by "Do it yourself" tasks to reinforce learning and ensure active engagement with the material. The subsequent chapters study specific classes of first order differential equations. Chapter 2 focuses on first order equations, including their definitions, key theorems, and special cases such as separable equations. Practical exercises are included to develop problem-solving skills. Chapter 3 covers linear differential equations, highlighting important methods such as the Euler-Lagrange approach and integrating factors. We will also examine Bernoulli equations, providing tools for solving a broad class of problems. In Chapter 4, we explore exact differential equations, discussing their properties and methods of solution. Techniques like integrating factors for nonexact equations are presented to expand your toolkit for tackling complex problems. The final chapter demonstrates the application of the theory to real-world modelling situations. We investigate how differential equations can describe phenomena in population dynamics, cooling processes, mixing, and elementary mechanics. These examples demonstrate the practical relevance of the concepts covered. An appendix on the review of integration techniques supports the main content, offering definitions, properties, tables of common integrals, and illustrative examples to strengthen your understanding. This textbook aims to make the study of differential equations accessible, engaging, and applicable to various fields.
Wybrane zagadnienia matematyki dyskretnej
Jolanta Pozorska, Izabela Zamorska
Matematyka dyskretna to, zgodnie z definicją, zbiorcza nazwa wszystkich działów matematyki, które zajmują się badaniem struktur nieciągłych, to znaczy zawierających zbiory co najwyżej przeliczalne, czyli właśnie dyskretne. Pozycja składa się z 7 rozdziałów, z których każdy omawia inne zagadnienie z zakresu matematyki dyskretnej, m.in. zbiory, indukcję matematyczną, elementy kombinatoryki i teorii liczb czy arytmetykę modularną. Każdy rozdział zawiera zadania, jak również wskazówki i rozwiązania zadań, natomiast ostatni podrozdział stanowi wykaz literatury tematu. Zachęcamy do sięgnięcia po publikację.
