Mathematics, 2023 The potential for widespread applications of the geometric and mapping properties of functions of a complex variable has motivated this article. On the other hand, the basic or quantum (or q-) derivatives and the basic or quantum (or q-) integrals are ...

Subclasses of Analytic Functions with Negative Coefficients Involving q-Derivative Operator
Science and Technology Indonesia, 2022 Let A denote the class of functions f which are analytic in the open unit disk U. The subclass of A consisting of univalent functions is denoted by M.

A Class of k-Symmetric Harmonic Functions Involving a Certain q-Derivative Operator
Mathematics, 2021 In this paper, we introduce a new class of harmonic univalent functions with respect to k-symmetric points by using a newly-defined q-analog of the derivative operator for complex harmonic functions.

Ukrains'kyi Matematychnyi Zhurnal, 2021 We establish several general results concerning the partial sums of meromorphically starlike functions defined by means of a certain class of q -derivative (or q -difference) operators.

Open Journal of Mathematical Analysis, 2021 In this paper, the \(q\)-derivative operator and the principle of subordination were employed to define a subclass \(\mathcal{B}_q(\tau,\lambda,\phi)\) of analytic and bi-univalent functions in the open unit disk \(\mathcal{U}\).

A possible deformed algebra and calculus inspired in nonextensive thermostatistics [PDF]
, 2004 We present a deformed algebra related to the q-exponential and the q-logarithm functions that emerge from nonextensive statistical mechanics. We also develop a q-derivative (and consistently a q-integral) for which the q-exponential is an eigenfunction ...
