Applications Laguerre Polynomials for Families of Bi-Univalent Functions Defined with (p,q)-Wanas Operator

Abstract

In current manuscript, using Laguerre polynomials and (p−q)-Wanas operator, we identify upper bounds a2 and a3 which are first two Taylor-Maclaurin coefficients for a specific bi-univalent functions classes W∑(η,δ,λ,σ,θ,α,β,p,q;h) and K∑(ξ,ρ,σ,θ,α,β,p,q;h) which cover the convex and starlike functions. Also, we discuss Fekete-Szegö type inequality for defined class.
