Some Properties of Janowski Symmetrical Functions
Symmetry, 2022 In our present work, the concepts of symmetrical functions and the concept of spirallike Janowski functions are combined to define a new class of analytic functions. We give a structural formula for functions in Sη,μ(F,H,λ), a representation theorem, the radius of starlikeness estimates, covering and distortion theorems and integral mean inequalities ...

Some General Classes of q-Starlike Functions Associated with the Janowski Functions [PDF]
Symmetry, 2019 By making use of the concept of basic (or q-) calculus, various families of q-extensions of starlike functions of order α in the open unit disk U were introduced and studied from many different viewpoints and perspectives. In this paper, we first investigate the relationship between various known classes of q-starlike functions that are ...

On Some Classes of Harmonic Functions Associated with the Janowski Function
Mathematics, 2023 In this paper, we introduce some classes of univalent harmonic functions with respect to the symmetric conjugate points by means of subordination, the analytic parts of which are reciprocal starlike (or convex) functions. Further, we discuss the geometric properties of the classes, such as the integral expression, coefficient estimation, distortion ...

Properties of q-Symmetric Starlike Functions of Janowski Type
Symmetry, 2022 The word “symmetry” is a Greek word that originated from “symmetria”. It means an agreement in dimensions, due proportion, and arrangement; however, in complex analysis, it means objects remaining invariant under some transformation. This idea has now been recently used in geometric function theory to modify the earlier classical q-derivative ...
