Certain Classes of Meromorphic Functions with Positive and Missing Coefficients

Certain Subclasses of Meromorphically P-Valent Functions With Positve or Negative Coeficients Using Differential Operator

“…Where is the class of meromorphically pvalent convex functions of order ( (with positive or negative coefficients depending upon the value of the nonzero constant B) (see Duren [6], Goodman [7] and Srivastava and Owa [18]); (iv) , where is the class of meromorphically convex functions of order ( with negative coefficients (see Uralegaddi and Ganigi [19] and Srivastava et.al. [17]); Some other subclasses of the class were studied (for example) by Cho et al [4,5], Altintas et al [1], Liu [12], Liu and Srivastava [13,14], Joshi et al, [11], Raina and Srivastava [15] and Aouf and Shammaky [2]. The aim of this paper is to proving a systematic investigation of the various interesting properties and characteristics of functions belonging to the following subclasses and of the general class which we introduced above: Furthermore, since the condition is not actually a requirement for the definition (1.4), we may set in (1.4) and observe that the class consisting of meromorphically p-valent starike functions of order with positive coefficients given by (1.10).…”
