In the present paper, a subclass of analytic and biunivalent functions by means of
Gegenbauer polynomials is introduced. Certain coefficients bound for functions belonging to …

Three subclasses of analytic and bi-univalent functions are introduced through the use of q−
Gegenbauer polynomials, which are a generalization of Gegenbauer polynomials. For …

By using the generalization of the neutrosophic q-Poisson distribution series, we introduce a
new subclass of analytic and bi-univalent functions defined in the open unit disk. We then …

By means of (p, q)− Lucas polynomials, a class of Bazilevic functions of order ϑ+ iδ in the
open unit disk U of analytic and bi-univalent functions is introduced. Further, we estimate …

In the current study, we provide a novel qualitative new subclass of analytical and bi-
univalent functions in the symmetry domain U defined by the use of Gegenbauer …

The present paper introduces a new class of bi-univalent functions defined on a symmetric
domain using Gegenbauer polynomials. For functions in this class, we have derived the …

Using the recently introduced Sălăgean integro-differential operator, three new classes of bi-
univalent functions are introduced in this paper. In the study of bi-univalent functions …

By means of Chebyshev polynomials, a class of Bazilevič functions of order α+ i β α+ i β in
the open unit disk UU of analytic and bi-univalent functions is introduced. Further, we …

Subclasses of analytic and bi-univalent functions have been extensively improved and
utilized for estimating the Taylor–Maclaurin coefficients and the Fekete–Szegö functional. In …

In this paper, make use of the Horadam polynomials, we introduce a comprehensive
subclass of analytic and bi-univalent functions. For functions belonging to this class we …
