Invariant Approximations for Noncommuting Generalized $(\mathcal I,\mathcal J)$-Nonexpansive Mappings in $q$-Normed Spaces


Hemant Kumar Nashine




We obtain common fixed points as invariant approximation for noncommuting generalized $(\mathcal I,\mathcal J)$-nonexpansive mappings in $q$-normed space which is not necessarily locally convex. Our results improve, extend and generalize various existing known results in the literature.
