In recent years, the usage of the q‐derivative and symmetric q‐derivative operators is
significant. In this study, firstly, many known concepts of the q‐derivative operator are …

In recent years, using the idea of analytic and bi-univalent functions, many ideas have been
developed by different well-known authors, but the using Gegenbauer polynomials along …

The q-derivative and Hohlov operators have seen much use in recent years. First, numerous
well-known principles of the q-derivative operator are highlighted and explained in this …

The logarithmic functions have been used in a verity of areas of mathematics and other
sciences. As far as we know, no one has used the coefficients of logarithmic functions to …

In mathematics, physics, and engineering, orthogonal polynomials and special functions
play a vital role in the development of numerical and analytical approaches. This field of …

In this paper, we introduce two new subclasses of bi-univalent functions using the q-Hermite
polynomials. Furthermore, we establish the bounds of the initial coefficients υ 2, υ 3, and υ 4 …

In our present investigation, we extend the idea of q-symmetric derivative operators to
multivalent functions and then define a new subclass of multivalent q-starlike functions. For …

In this paper, using the basic concepts of symmetric q‐calculus operator theory, we define a
symmetric q‐difference operator for m‐fold symmetric functions. By considering this …

In this paper, we make use of the concept of q− calculus in the theory of univalent functions,
to obtain the bounds for certain coefficient functional problems of Janowski type starlike …

In this paper, the theory of symmetric q-calculus and conic regions are used to define a new
subclass of q-starlike functions involving a certain conic domain. By means of this newly …
