In this post we will see the book Lectures on the Theory of Functions of a Complex Variable by Yu. V. Sidorov, M. V. Fedoryuk , M. I. Shabunin. About the book This book is based on more than ten years experience in teaching the theory of functions of a complex variable at the Moscow Physics and Technology Institute. It is a textbook for students of universities and institutes of technology with an advanced mathematical program. We believe that it can also be used for independent study. We have stressed the methods of the theory that are often used in applied sciences. These methods include series expansions, conformal mapping, application of the theory of residues to evaluating definite integrals, and asymptotic methods. The material is structured in a way that will give the reader the maximum assistance in mastering the basics of the theory. To this end we have provided a wide range of worked-out examples. We hope that these will help the reader acquire a deeper understanding of the theory and experience in problem solving. The book was translated from Russian by Eugene Yankovsky and was first published by Mir in 1985.

The modern engineer often has to do with problems that require a sound mathematical background and set skills in the use of diverse mathematical methods. Expanding the mathematical outlook of the engineer contributes appreciably to new advances in technology. The theory of functions of a complex variable, operational calculus, and stability theory are most important for applications.  The present text is designed for students of engineering colleges and also for practicing engineers who feel a need to refresh their knowledge of such important areas of mathematics. Each section of the text starts out with a brief review of the essentials of theory (propositions, definitions,  formulas). This is followed by examples with detailed solutions and exercises. The book contains about 1000 examples and problems to be solved by the student.  It would be impossible to acknowledge all the help, direct and indirect, that we have received in the preparation of this book, but certainly the many comments of Professor V.A. Trenogin, Head of the Mathematics Department at the Moscow Institute of Steel and Alloys, and of Associate Professor M.I. Orlov of the same department must be acknowledged. We are also greatful to members of the Applied Mathematics Department at the Kiev Engineering Construction Institute (head of department Associate Professor A.E. Zhuravel’) and to B. Tkachev (Krasnodar) and B.L. Tsabo (Sukhumi) for their helpful suggestions and criticism. Finally, it is a pleasure to acknowledge the help of Professors M.I. Vishik, F.I. Karpelevich, A.F. Leont’ev, and SJ. Pokhozhaev. Naturally, any errors that may remain in spite of all this assistance are our responsibility, and we would appreciate being advised of them.  M.L. Krasnov  A.I.

Expanding the mathematical outlook of the engineer contributes appreciably to new advances in technology. The theory of functions of a complex variable, operational calculus, and stability theory are most important for applications.  The present text is designed for students of engineering colleges and also for practicing engineers who feel a need to refresh their knowledge of such important areas of mathematics. Each section of the text starts out with a brief review of the essentials of theory (propositions, definitions,  formulas). This is followed by examples with detailed solutions and exercises. The book contains about 1000 examples and problems to be solved by the student.  It would be impossible to acknowledge all the help, direct and indirect, that we have received in the preparation of this book, but certainly the many comments of Professor V.A. Trenogin, Head of the Mathematics Department at the Moscow Institute of Steel and Alloys, and of Associate Professor M.I. Orlov of the same department must be acknowledged. We are also greatful to members of the Applied Mathematics Department at the Kiev Engineering Construction Institute (head of department Associate Professor A.E. Zhuravel’) and to B. Tkachev (Krasnodar) and B.L. Tsabo (Sukhumi) for their helpful suggestions and criticism. Finally, it is a pleasure to acknowledge the help of Professors M.I. Vishik, F.I. Karpelevich, A.F. Leont’ev, and SJ. Pokhozhaev. Naturally, any errors that may remain in spite of all this assistance are our responsibility, and we would appreciate being advised of them.  M.L. Krasnov  A.I.
