On some summation formulas

open access: yesDemonstratio Mathematica, 2022
In this note, we derive a finite summation formula and an infinite summation formula involving Harmonic numbers of order up to some order by means of several definite integrals.

Simultaneous Contour Method of a Trigonometric Integral by Prudnikov et al.

open access: yesMathematics, 2021
In this present work we derive, evaluate and produce a table of definite integrals involving logarithmic and exponential functions. Some of the closed form solutions derived are expressed in terms of elementary or transcendental functions.

Reduction Formulae of 2-refined Neutrosophic Integrals and their Applications [PDF]

open access: yesNeutrosophic Sets and Systems
The main aim of this manuscript is to establish for the first time the reduction formulae of 2-refined neutrosophic indefinite integrals (shortly, RF2RNII) which have double indeterminacy I1 and I2 respectably.

The Multivariable Aleph-function involving the Generalized Mellin-Barnes Contour Integrals

open access: yesCubo, 2020
In this paper, we have evaluated three definite integrals involving the product of two hypergeometric functions and multivariable Aleph-function. Certain special cases of the main results are also pointed out.

Further Equivalent Binomial Sums

open access: yesComptes Rendus. Mathématique, 2021
Five binomial sums are extended by a free parameter $m$, that are shown, through the generating function method, to have the same value. These sums generalize the ones by Ruehr (1980), who discovered them in the study of two unexpected equalities between

Integrals of Frullani type and the method of brackets

open access: yesOpen Mathematics, 2017
The method of brackets is a collection of heuristic rules, some of which have being made rigorous, that provide a flexible, direct method for the evaluation of definite integrals.
