On new subclasses of meromorphically convex functions with positive coefficients

Abstract

In this paper we introduce and study a new subclass of meromorphically uniformly convex functions with positive coefficients defined by a bessel operator and obtain coefficient estimates, growth and distortion theorem, radius of
convexity, integral transforms, convex linear combinations, convolution properties and $\delta -$neighborhoods for the class $\sigma _{p} (\alpha , \tau ,c).$
