Abstract

This note is a verification on the relations between almost linear and nearly additive maps; and the continuity of almost multiplicative nearly additive maps. Also we consider the stability of nearly additive and almost linear maps.

Keywords: stability, linear maps, almost linear maps, nearly additive maps, almost multiplicative maps
