Functional Equations in Mathematical Analysis

Thestability problem for approximate homomorphisms, or the Ulam stability problem,was posed by S. M. Ulam in the year 1941.The solutionof this problem for various classes ofequationsis an expanding area of research.In particular, thepursuit ofsolutions to the Hyers-Ulam and Hyers-Ulam-Rassiasstability problemsforsets offunctional equations and ineqalities has led toan outpouring of recentresearch. This volume, dedicated toS. M. Ulam, presents the most recent resultsonthe solution to Ulamstability problems forvarious classes offunctional equations and inequalities. Comprised ofinvitedcontributionsfromnotable researchers and experts, this volumepresentsseveral importanttypes offunctional equations and inequalitiesand theirapplications to problems inmathematical analysis, geometry,physics and applied mathematics. "Functional Equations in Mathematical Analysis"is intended forresearchers and students in mathematics, physics, and other computational and applied sciences.
