  Article:   CONVOLUTIONS OF UNIVALENT FUNCTIONS WITH NEGATIVE COEFFICIENTS USING A GENERALIZED SĂLĂGEAN OPERATOR.

Authors:  ADRIANA CĂTAȘ.
 
       
         
  Abstract:   The object of this paper is to derive several interesting properties of the class
Tj(n, γ, α, λ)
consisting of analytic and univalent functions with negative coefficients. Integral operators and modified Hadamard products of several functions belonging to the class Tj(n, γ, α, λ) are studied. 

Key words and phrases. Analytic function, univalent function, generalized Sălăgean operator, negative coefficients, modified Hadamard product, integral operator.
