A well-established Soviet university textbook on complex analysis, expanded for its second edition with a new chapter on operational calculus alongside the original treatment of multivalued analytic functions and elementary asymptotic methods, subjects less commonly given such detailed textbook attention. Mikhail Vasilievich Fedoryuk (1934-1990), the best known of the three co-authors, was a leading specialist in asymptotic analysis and the author of the standard Russian monograph on the saddle-point method, cited within this book's own bibliography; his expertise shaped the text's unusually thorough coverage of asymptotic techniques for a course aimed at engineering-physics students. Prepared for the demanding curricula of Soviet technical-physics institutes, the book has remained continuously in print in Russia across further editions into the twenty-first century, making it a standard reference still assigned in university courses on complex analysis today.
