Definite Integral of Logarithmic Functions in Terms of the Incomplete Gamma Function

open access: yesMathematics, 2021
In this article we derive some entries and errata for the book of Gradshteyn and Ryzhik which were originally published by Bierens de Haan. We summarize our results using tables for easy reading and referencing.

Uniform asymptotics for the incomplete gamma functions starting from negative values of the parameters [PDF]

open access: yes, 1996
We consider the asymptotic behavior of the incomplete gamma functions gamma(-a,-z) and Gamma(-a,-z) as a goes to infinity. Uniform expansions are needed to describe the transition area z~a in which case error functions are used as main approximants.

Some inequalities for multiplicative tempered fractional integrals involving the λ-incomplete gamma functions

open access: yesAIMS Mathematics, 2021
In this paper, we introduce a class of the multiplicative tempered fractional integral operators. Then, we investigate two Hermite–Hadamard type inequalities for this class. By using the established identity and the multiplicative convexity, we establish

Computing hypergeometric functions rigorously [PDF]

open access: yes, 2016
We present an efficient implementation of hypergeometric functions in arbitrary-precision interval arithmetic. The functions ${}_0F_1$, ${}_1F_1$, ${}_2F_1$ and ${}_2F_0$ (or the Kummer $U$-function) are supported for unrestricted complex parameters and ...

Some New Results for the $\mathscr{M}$-Transform Involving the Incomplete $I$-Functions [PDF]

open access: yesSahand Communications in Mathematical Analysis
Integral transformations are crucial for solving a variety of actual issues. The right choice of integral transforms aids in simplifying both integral and differential problems into a solution-friendly algebraic equation.

Fractional calculus and integral transforms of the product of a general class of polynomial and incomplete Fox–Wright functions

open access: yesAdvances in Difference Equations, 2020
Motivated by a recent study on certain families of the incomplete H-functions (Srivastava et al. in Russ. J. Math. Phys. 25(1):116–138, 2018), we aim to investigate and develop several interesting properties related to product of a more general ...

Derangements and the 𝑝-adic incomplete gamma function

open access: yesTransactions of the American Mathematical Society, 2022
We introduce a p p -adic analogue of the incomplete gamma function. We also introduce quantities ( m m -values) associated to a function on natural numbers and prove a new characterization of p p -adic continuity for functions with p p -integral m m -values ...

New fractional inequalities of Hermite–Hadamard type involving the incomplete gamma functions

open access: yesJournal of Inequalities and Applications, 2020
A specific type of convex functions is discussed. By examining this, we investigate new Hermite–Hadamard type integral inequalities for the Riemann–Liouville fractional operators involving the generalized incomplete gamma functions.
