and Applied Analysis 3 We can describe that latter result saying that the Cauchy functional equation 2.8 is HyersUlam stable (or has the Hyers-Ulam stability) in the class of functions Y . For examples of various possible definitions of stability for functional equations and some discussions on them we refer to 9 . The result of Hyers was extended by Aoki(More)
Let I a, b , J c, d be closed, bounded, and nondegenerate i.e., neither of them consists of a single point real intervals, and let f : I → I, F : J → J be continuous functions. The aim of this paper is to discuss, under some additional assumptions on the maps f and F, the problem of topological conjugacy of f and F. More precisely, we investigate the(More)
