Nielsen’s Generalized Polylogarithms [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 1986
Properties (in particular functional relations and special values) of the functions \[ (-1)^{n+p-1}(n-1)! p! S_{n,p}(z)=\int^{1}_{0}\log^{n-1}t \log^ p(1-zt)(dt/t), \] \[ (-1)^{n+p-1}(n-1)! p! L_{n,p}(z)=\int^{z}_{0}\log^{n-1}t \log^ p(1-t)(dt/t), \] \[ (-1)^{n-1}(n-1)! p!

Approximation of Caputo Fractional Derivative and Numerical Solutions of Fractional Differential Equations

open access: yesFractal and Fractional, 2023
In this paper, we consider an approximation of the Caputo fractional derivative and its asymptotic expansion formula, whose generating function is the polylogarithm function.

ON A CERTAIN CONVOLUTION OF POLYLOGARITHMS [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2011
AbstractIn this paper, we consider certain double series analogous to Tornheim’s double series and real analytic Eisenstein series. By computing double integrals in two ways, we express the double series as a sum of products of polylogarithms. The technique generalises one given by Kanemitsu, Tanigawa and Yoshimoto.

Polylogarithms and the Asymptotic Formula for the Moments of Lebesgue’s Singular Function

open access: yesМоделирование и анализ информационных систем, 2016
Recall the Lebesgue's singular function. We define a Lebesgue's singular function \(L(t)\) as the unique continuous solution of the functional equation$$L(t) = qL(2t) +pL(2t-1),$$where \(p,q>0\), \(q=1-p\), \(p\ne q\).The moments of Lebesque' singular

Relations for Nielsen polylogarithms

open access: yesJournal of Approximation Theory, 2015
The multiple polylogarithms are defined by \[ \text{Li}_{a_1,\dots,a_k}(x)= \sum_{n_1>\cdots> n_k} {x^{n_1}\over n^{a_1}_1\cdots n^{a_k}_k}. \] The sum \(w= a_1+\cdots+ a_n\) is called the weight of the function. The authors consider also two associated multiple special functions: the multiple Claussen functions \[ \text{Cl}_{a_1,\dots,a_k}(\tau ...

Degenerate polyexponential functions and type 2 degenerate poly-Bernoulli numbers and polynomials

open access: yesAdvances in Difference Equations, 2020
The polyexponential functions were introduced by Hardy and rediscovered by Kim, as inverses to the polylogarithm functions. Recently, the type 2 poly-Bernoulli numbers and polynomials were defined by means of the polyexponential functions. In this paper,

Evaluating master integrals in non-factorizable corrections to t-channel single-top production at NNLO QCD

open access: yesJournal of High Energy Physics, 2023
We studied the two-loop non-factorizable Feynman diagrams for the t-channel single-top production process in quantum chromodynamics. We present a systematic computation of master integrals of the two-loop Feynman diagrams with one internal massive ...

The Polylogarithm Function in Julia

open access: yesCoRR, 2020
The polylogarithm function is one of the constellation of important mathematical functions. It has a long history, and many connections to other special functions and series, and many applications, for instance in statistical physics. However, the practical aspects of its numerical evaluation have not received the type of comprehensive treatments ...

Hurwitz-Lerch Type Multi-Poly-Cauchy Numbers

open access: yesMathematics, 2019
In this paper, we define Hurwitz–Lerch multi-poly-Cauchy numbers using the multiple polylogarithm factorial function. Furthermore, we establish properties of these types of numbers and obtain two different forms of the explicit formula using ...
