A Family of Bi-Univalent Functions Defined by (p, q)-Derivative Operator Subordinate to a Generalized Bivariate Fibonacci Polynomials

Making use of a generalized bivariate Fibonacci polynomials, we propose a family of normalized regular functions psi(zeta) = c + d(2)zeta(2) + d(3)zeta(3) + <middle dot> <middle dot> <middle dot>, which are bi-univalent in the disc {zeta E C : zeta < 1} involving (p, q)-derivative operator. We find estimates on the coefficients d(2) , d(3) and the Fekete-Szego inequality for members of this family. New implications of the primary result as well as pertinent links to previously published findings are also provided.
