Radii Problems of Certain Subclasses of Analytic Functions With Fixed Second Coefficients

Abstract

Abstract. The purpose of the present paper is to study certain radii problems for the functionwhere β is a positive real number, γ is a complex number such that γ +β = 0 and the function F (z) varies various subclasses of analytic functions with fixed second coefficients. Relevant connections of the results presented herewith various well-known results are briefly indicated.
