Some q-Identities derived by the ordinary derivative operator [PDF]

open access: yes, 2023
In this paper, we investigate applications of the ordinary derivative operator, instead of the $q$-derivative operator, to the theory of $q$-series. As main results, many new summation and transformation formulas are established which are closely related

A certain ( p , q ) $(p,q)$ -derivative operator and associated divided differences [PDF]

open access: yes, 2016
Recently, Sofonea (Gen. Math. 16:47-54, 2008) considered some relations in the context of quantum calculus associated with the q-derivative operator D q $D_{q}$ and divided difference. As applications of the post-quantum calculus known as the ( p , q ) $(

Fractional variational problems with the Riesz-Caputo derivative [PDF]

open access: yes, 2012
In this paper we investigate optimality conditions for fractional variational problems, with a Lagrangian depending on the Riesz-Caputo derivative. First we prove a generalized Euler-Lagrange equation for the case when the interval of integration of the ...

A Note on the q-Derivative Operator [PDF]

open access: yes, 1993
The following statement is proved. If the q-derivative operator Dq is defined by [formula] for functions ƒ which are differentiable at x = 0, then we have for every positive integer n[formula] for every function ƒ whose nth derivative at x = 0 exists. We

Applications of Higher-Order q-Derivative to Meromorphic q-Starlike Function Related to Janowski Function [PDF]

open access: yes, 2022
By making use of a higher-order q-derivative operator, certain families of meromorphic q-starlike functions and meromorphic q-convex functions are introduced and studied.

Kober fractional q-derivative operators [PDF]

open access: yes, 2011
In the present paper, we define right and left sided Kober fractional q-derivative operators and show that these derivative operators are left inverse operators of Kober fractional q-integral operators.
