Authors: ALI AKBAR AREFIJAMAAL, FAHIMEH ARABYANI NEYSHABURI

Abstract: In this paper we extend the notion of approximate dual to fusion frames and present some approaches to obtain alternate dual and approximate alternate dual fusion frames. We also study the stability of alternate dual and approximate alternate dual fusion frames.

Keywords: Fusion frames, alternate dual fusion frames, approximate alternate duals, Riesz fusion bases,
