Approximate Solution of Mixed Problem for Telegrapher Equation with Homogeneous Boundary Conditions of First Kind Using Special Functions

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2021
The mixed problem for the telegraph equation well-known in electrical engineering and electronics, provided that the line is free from distortions, is reduced to a similar problem for one-dimensional inhomogeneous wave equation. An effective way to solve

Analyticity of the Free Energy of a Closed 3-Manifold

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
The free energy of a closed 3-manifold is a 2-parameter formal power series which encodes the perturbative Chern-Simons invariant (also known as the LMO invariant) of a closed 3-manifold with gauge group U(N) for arbitrary N.

An Operational Matrix Method Based on Poly-Bernoulli Polynomials for Solving Fractional Delay Differential Equations

open access: yesComputation, 2020
In this work, we derive the operational matrix using poly-Bernoulli polynomials. These polynomials generalize the Bernoulli polynomials using a generating function involving a polylogarithm function.

Lepton-pair scattering with an off-shell and an on-shell photon at two loops in massless QED

open access: yesJournal of High Energy Physics, 2023
We compute the two-loop QED helicity amplitudes for the scattering of a lepton pair with an off-shell and an on-shell photon, 0 → ℓ ℓ ¯ γγ $$ \ell \overline{\ell}\gamma \gamma $$ *, using the approximation of massless leptons.

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review

open access: yesAdvanced Physics Research, Volume 5, Issue 7, July 2026.
Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

On the Kernel of the Symbol Map for Multiple Polylogarithms [PDF]

open access: yes, 2012
The symbol map (of Goncharov) takes multiple polylogarithms to a tensor product space where calculations are easier, but where important differential and combinatorial properties of the multiple polylogarithm are retained.

Integral representation and functional inequalities involving generalized polylogarithm [PDF]

open access: yes
The purpose of this manuscript is to derive two distinct integral representations of the generalized polylogarithm using two different techniques. The first approach involves the Dirichlet series and its Laplace representation, which leads to a single ...
