ON APPROXIMATELY(p,q)-WRIGHT AFFINE FUNCTIONS AND INNER PRODUCT SPACES
收藏 引用
Acta Mathematica Scientia 2016年 第2期36卷 593-601页
作者: anna bahyrycz Magdalena PISZCZEK Institute of Mathematics Pedagogical University
We prove, using the fixed point approach, some results on hyperstability (in normed spaces) of the equation that defines the generalization of p-Wright affine functions and show that they yield a simple characteriza... 详细信息

ON AN EQUATION CHARACTERIZING MULTI-CAUCHY-JENSEN MAPPINGS AND ITS HYERS-ULAM STABILITY
收藏 引用

作者: anna bahyrycz Krzysztof CIEPLINSKI Jolanta OLKO Institute of Mathematics Pedagogical University AGH University of Science and Technology Faculty of Applied Mathematics
In this paper, we give two characterizations of multi-Cauchy-Jensen mappings. One of them reduces the system of n equations defining these mappings to a single functional equation. We also prove, using the fixed point... 详细信息
