Title: Existence and stability of solutions to nonlinear impulsive differential equations in beta-normed spaces Authors: Jinrong Wang (Guizhou Univ., Guiyang, Guizhou, China) Yuruo Zhang (Guizhou Univ., Guiyang, Guizhou, China) Abstract: In this article, we consider nonlinear impulsive differential equations in beta-normed spaces. We give new concepts of beta-Ulam's type stability. Also we present sufficient conditions for the existence of solutions for impulsive Cauchy problems. Then we obtain generalized beta-Ulam-Hyers-Rassias stability results for the impulsive problems on a compact interval. An example illustrates our main results. Submitted February 3, 2014.
