Common Fixed Point for Affine Self Maps Invariant Approximation in p-normed Spaces

Common fixed point results for new classes of non-commuting self-maps and non-expansive. Within the class of all self-maps f and T of a w?starshaped subset M of x where f is affine or w?affine. We apply them to obtain several invariant approximation results which unify, extend, and complement well-known results.
