Abstract
Let S be a self mapping on a complex normed space X. In this paper, we study the class of mappings satisfying the following condition
Sigma(0 <= k <= m) (-1)(m-k)((k) (m))parallel to S(k)x - S(k)y parallel to(p) = 0
for all x, y is an element of X, where m is a positive integer. We prove some of the properties of these classes of mappings.
