Refinements of some recent inequalities for certain special functions

Mochamed Akkouchi , Mochamed Amine Ighachane

Abstract

The aim of this paper is to give some refinements to several inequalities, recently etablished, by P.K. Bhandari and S.K. Bissu in [Inequalities via Hölder’s inequality, Scholars Journal of Research in Mathematics and Computer Science, 2 (2018), no. 2, 124–129] for the incomplete gamma function, Polygamma functions, Exponential integral function, Abramowitz function, Hurwitz-Lerch zeta function and for the normalizing constant of the generalized inverse Gaussian distribution and the Remainder of the Binet’s first formula for ln Γ(x).

Keywords:

Hölder’s inequalities , incomplete Gamma function , exponential integral function , Hurwitz-Lerch zeta function , Abramowitz function , Binet’s first formula
