Approximation Properties of Solutions of a Mean Value-Type Functional Inequality, II
Let <i>X</i> be a commutative normed algebra with a unit element <i>e</i> (or a normed field of characteristic different from 2), where the associated norm is sub-multiplicative. We prove the generalized Hyers-Ulam stability of a mean value-type functional equation, <inlin...
