In this paper, we introduce a new subclass of bi-univalent functions of complex order, using the symmetric q-derivative with subordination principles. We obtain upper bounds for the coefficients |c2|, |c3| and estimate an upper bound for the Fekete–Szegő

In this work, we introduce a new subclass of bi-univalent functions using the (p,q)-derivative operator and the concept of subordination to generalized Laguerre polynomials Ltς(k), which satisfy the differential equation ky″+(1+ς−k)y′+ty=0, with 1+ς>0, k∈

Fekete-Szegö functional of classes of analytic functions involving the q-derivative operator
Applied Mathematical Sciences, 2020Let A denote the class of functions which are analytic in the open unit disc U = {z ∈ C : |z| < 1}. In this paper, we introduce new classes of analytic functions involving q-derivative operator defined on U.
