Let A_p denote the class of functions f(Z)=??a_(p+n)z^(p+n) (p=1,2,3,…) which are holomorphic in the unit disc △={Z:|Z|<1}and M_p(α) the class of P-valently α-convex function f(Z) which satisfy the condition
Re {(1-α)Zf'(Z)/f(Z)+α(1+Zf"(Z)/f'(Z))}>0 for Z∈△ and nonnegative number α, The purpose of this note is to show properties of function f(Z)∈M_p(α).
