Asymptotic Expansion of the Modified Exponential Integral Involving the Mittag-Leffler Function [PDF]

open access: yesMathematics, 2020
We consider the asymptotic expansion of the generalised exponential integral involving the Mittag-Leffler function introduced recently by Mainardi and Masina [Fract. Calc. Appl. Anal. 21 (2018) 1156−1169].

Indefinite integrals involving the exponential integral function [PDF]

open access: yesIntegral Transforms and Special Functions, 2021
The exponential integral function Ei(x) is given as an indefinite integral of an elementary expression. This allows a second-order linear differential equation for the function to be constructed, which is of conventional form.

On Some Bounds for the Exponential Integral Function

open access: yesJournal of Nepal Mathematical Society, 2021
In 1934, Hopf established an elegant inequality bounding the exponential integral function. In 1959, Gautschi established an improvement of Hopf’s results. In 1969, Luke also established two inequalities with each improving Hopf’s results. In 1997, Alzer

A HARMONIC MEAN INEQUALITY CONCERNING THE GENERALIZED EXPONENTIAL INTEGRAL FUNCTION

open access: yesAdvances in Mathematics: Scientific Journal, 2021
In this paper, we prove that for $s\in(0,\infty)$, the harmonic mean of $E_k(s)$ and $E_k(1/s)$ is always less than or equal to $\Gamma(1-k,1)$. Where $E_k(s)$ is the generalized exponential integral function, $\Gamma(u,s)$ is the upper incomplete gamma ...
