This proceedings volume covers research in key areas of applied mathematical analysis, and gathers works presented at the international conference "Concord-90," in honor of the 90th birthday of Professor Constantin Corduneanu (1928-2018). The event - which Professor Corduneanu was able to attend - was held at Ural Federal University in Ekaterinburg, Russia, on July 26-28, 2018.
Professor Corduneanu's research in mathematical analysis spanned nearly seven decades and explored a range of important issues in the field, including studies of global existence, stability problems, and oscillation theory, with special emphasis on various classes of nonlinear equations. He published over two hundred articles and several books, including "Almost Periodic Oscillations and Waves" (Springer, 2009).
In this volume the reader will find selected, peer-reviewed articles from seven fields of research - Differential Equations, Optimal Control and Stabilization; Stochastic Methods; Topology and Functions Approximation; Mathematical Biology and Bioinformatics; Mathematical Modeling in Mining; Mathematical Modeling in Economics; and Computer Science and Image Processing - which honor and reflect Professor Corduneanu's legacy in the fields of oscillation, stability and control theory.
