Abstract
This paper is emphasizing on the new analytic odd function defined using Salagean differential operator H(m, z) in the open unit disc. The main objective is to study the ratio of the function H(m, z) to its sequence of partial sum. Also, to determine the sharp upper bound for Re {H(m, z)/Hn(m, z)}, Re {Hn(m, z)/H(m, z)}, Re {H'(m, z)/H'n(m, z)} and Re {H'n(m, z)/H'(m, z)}.
