摘要
In the present paper, we propose to introduce a new subclass of biunivalent analytic functions T-Sigma(lambda, gamma) (0 < lambda <= 1, gamma >= 0) which is defined by making use of the generalized Laguerre polynomials in the open unit disk del. We derive upper bounds for the coefficients vertical bar a(2)vertical bar, vertical bar a(3)vertical bar and discuss Fekete-Szego problem for the functions belonging to the new introduced class T-Sigma(lambda, gamma).
