Generalized Polynomials and Their Unification and Extension to Discrete Calculus

Abstract

In this paper we introduce a comprehensive and expanded framework for generalized calculus and generalized polynomials in discrete calculus. Our focus is on (Formula presented.) -time scales. Our proposed approach encompasses both difference and quantum problems making it highly adoptable. Our framework employs forward and backward jump operators to create a unique approach. We use a weighted jump operator (Formula presented.) that combines both jump operators in a convex manner. This allows us to generate a time scale (Formula presented.) which provides a new approach to discrete calculus. This beneficial approach enables us to define a general symmetric derivative on time scale (Formula presented.) which produces various types of discrete derivatives and forms a basis for new discrete calculus. Moreover we create some polynomials on (Formula presented.) -time scales using the (Formula presented.) -operator. These polynomials have similar properties to regular polynomials and expand upon the existing research on discrete polynomials. Additionally we establish the (Formula presented.) -version of the Taylor formula. Finally we discuss related binomial coefficients and their properties in discrete cases. We demonstrate how the symmetrical nature of the derivative definition allows for the incorporation of various concepts and the introduction of fresh ideas to discrete calculus. © 2023 Elsevier B.V.
