Автор:Jonathan M. Borwein, Jon D. Vanderwerff Год: 2010 Издание: [не указанo] Страниц: 532 ISBN: 0521850053 The product of a collaboration of over 15 years, this volume is unique because it focuses on convex functions themselves, rather than on convex analysis. The authors explore the various classes and their characteristics, treating convex functions in both Euclidean and Banach spaces.
