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

In current manuscript, using Laguerre polynomials and (p − q) -Wanas operator, we identify upper bounds a 2 and a 3 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. [ABSTRACT FROM AUTHOR]
