Discrete weighted pseudo-almost automorphy and applications

We deal with discrete weighted pseudo almost automorphy which extends some classical concepts and systematically explore its properties in banach space including a composition result. as an application,we establish some sufficient criteria for the existence and uniqueness of the discrete weighted pseudo almost automorphic solutions to the volterra difference equations of convolution type and also to nonautonomous semilinear difference equations. some examples are presented to illustrate the main findings. © 2014 zhinan xia.
