Title: Weighted pseudo almost automorphic sequences and their applications Author: Syed Abbas (Indian Institute of Technology, Mandi, India) Abstract: In this article we define the concept of weighted pseudo almost automorphic sequence, and establish some basic properties of these sequences. Further, as an application, we show the existence, uniqueness and global attractivity of weighted pseudo almost automorphic sequence solutions of a neural network model. Submitted April 18, 2010.
