The approximation by the pertinent Euler-Lagrange-Jensen generalized quintic functional maps in quasi-Banach spaces

Abstract

The purpose of this paper is to approximate a given map by  the pertinent Euler-Lagrange-Jensen generalized quintic functional map, and by the Euler-Lagrange-Jensen alternative generalized quintic functional map. The obtained results are extensions of certain stability results from Banach  spaces to quasi-Banach spaces. The obtained results are supported by the examples.
