These functions are also called regular functions. Recently, meromorphic convex functions of order α have been defined and their properties have been investigated. In this paper, at first we introduce the meromorphic convex functions of inverse order α. In fact, convex functions of order revers α are a special class of analytic functions on unit open disk U that satisfy the following property:R(1+(f^' (z))/(zf^'' (z))) Manuscript profile -
