Lectures on Discrete Mathematics and Mathematical Logic by A. M. Shmyrina is a fascinating and deep immersion into the world of mathematical concepts, which become the basis for understanding not only the theoretical but also the practical side of mathematics. This work is not just a set of lectures, but a whole system of knowledge that helps the reader to realize the importance of discrete mathematics and logic in the modern world. Discrete mathematics is a field that studies structures that can be divided into separate, well-defined elements. This includes topics such as graphs, combinatorics, number theory, and logic. Shmyrin masterfully submits these complex concepts, making them accessible and understandable to students, graduate students and anyone interested in mathematics. The book will be especially useful for those who study computer science, programming and related disciplines, because discrete mathematics is the basis for algorithms and data structures. One of the key topics that the author raises is the relationship between mathematical logic and discrete mathematics. Shmyrin demonstrates how logical operations and statements form the basis for building mathematical proofs and algorithms. It not only explains the theory, but also offers many practical examples, which allows the reader to better assimilate the material. By reading this book, you will be able to see how abstract mathematical concepts are applied in real life, for example, in cryptography, information theory, and even in software development. The book "Lectures in Discrete Mathematics and Mathematical Logic" will be of interest not only to students and teachers, but also to those who want to expand their knowledge in the field of mathematics and logic. It is suitable for both beginners and more experienced readers who want to deepen their knowledge. Students of technical specialties, programmers and even fans of puzzles will find in it a lot of useful and fascinating. Style A. M. Shmyrin is distinguished by clarity and logical presentation. He skillfully combines theoretical aspects with practical tasks, which makes the learning process not only useful, but also interesting. The author is also known for his other work in mathematics and computer science, and his experience in teaching allows him to find an approach to different types of readers. Shmyrin is able to explain complex things in simple language, which makes his books especially valuable for self-study. In conclusion, “Lectures in Discrete Mathematics and Mathematical Logic” is not just a textbook, but a real find for anyone who wants to understand the basics of discrete mathematics and logic. This book will become a reliable companion for students, graduate students and anyone who aspires to knowledge in the field of mathematics. If you are looking for a quality and affordable guide to discrete mathematics, then work A. M. He will be your helper on this journey. Do not miss the opportunity to discover the world of logic and discrete structures, which will open new horizons in your understanding of mathematics and its practical application.
