Inverse and Incorrect Tasks by Vatulyan A. About. , Belyak O. A. , Sukhov D. Yu. , Yavruyan O. In. is a fascinating and in-depth study in mathematical modeling and problem theory that will be of interest to both students and professional researchers. The publication, published by Southern Federal University, is a unique combination of theoretical foundations and practical applications, making it an indispensable tool for anyone interested in mathematics and its application in various fields. The book immerses the reader in a world of inverse and incorrect problems that often arise in real life and scientific research. The authors consider in detail what inverse problems are, how they are formed and what methods are used to solve them. Unlike direct problems, where conditions are known and it is necessary to find a result, inverse problems require the researcher to restore the initial data on the results. This makes them especially difficult and interesting, because often the solution may not be the only one or even absent. For whom is this book intended? First of all, it will be useful to students of mathematical, physical and engineering specialties who seek to deepen their knowledge in the field of mathematical modeling . It will also attract the attention of graduate students and researchers engaged in research in the field of applied mathematics, physics and computer science. The book will be an excellent addition to educational materials and will help readers develop critical thinking and analytical skills. The topics raised in the book cover a wide range of issues, ranging from theoretical foundations to practical examples. The authors discuss methods for solving incorrect problems, which is an important part of mathematical analysis. They also focus on the importance of inverse problems in areas such as physics, biology, and economics. The reader will learn how these tasks can be used to model processes such as the spread of diseases, the dynamics of financial markets, and many others. The style of the authors is clear and accessible, which allows even complex concepts to be explained in simple language. Vatulyan, Belyak, Sukhov and Yavruyan are experienced teachers and researchers who know how to transfer their knowledge and experience to the reader . Their previous work is also noteworthy: they have published numerous articles and teaching aids, which have become the basis for many students and researchers. The book “Inverse and Incorrect Problems” is not just a textbook, but a real find for anyone who wants to understand how mathematics can be applied to solve real problems. It opens doors to the world of complex problems and offers the reader unique tools for solving them. If you are looking for inspiration for your studies or want to deepen your knowledge in mathematical modeling, this publication will become your reliable assistant. Do not miss the opportunity to get acquainted with this fascinating book, which will not only expand your horizons, but also help to develop the skills necessary for a successful career in science and technology. "Inverse and Incorrect Tasks" is a book that will become your faithful companion in the world of mathematics and scientific research.
