Fourier Series for the Tangent Polynomials, Tangent–Bernoulli and Tangent–Genocchi Polynomials of Higher Order

open access: yesAxioms, 2022
In this paper, the Fourier series expansion of Tangent polynomials of higher order is derived using the Cauchy residue theorem. Moreover, some variations of higher-order Tangent polynomials are defined by mixing the concept of Tangent polynomials with ...

Taylor expansion and the Cauchy Residue Theorem for finite-density QCD [PDF]

open access: yesProceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018), 2018
We present an update on our efforts to determine the Taylor coefficients of the $\mu/T$ expansion of the pressure for finite-density QCD. Here, we explore alternatives based on the Cauchy Residue Theorem, which allows us to use a discretized contour to ...

A Formal Proof of Cauchy’s Residue Theorem [PDF]

open access: yesLecture Notes in Computer Science, 2016
We present a formalization of Cauchy’s residue theorem and two of its corollaries: the argument principle and Rouché’s theorem. These results have applications to verify algorithms in computer algebra and demonstrate Isabelle/HOL’s complex analysis library.

Non-Integer Valued Winding Numbers and a Generalized Residue Theorem

open access: yesJournal of Mathematics, 2019
We define a generalization of the winding number of a piecewise C1 cycle in the complex plane which has a geometric meaning also for points which lie on the cycle.

Finding the Zeros of a High-Degree Polynomial Sequence

open access: yesJournal of Optimization, Differential Equations and Their Applications, 2021
A 1-parameter initial-boundary value problem for a linear spatially 1-dimensional homogeneous degenerate wave equation, posed in a space-time rectangle, in case of strong degeneracy, was reduced to a linear integro-differential equation of convolution ...

Efficient Numerical Quadrature for Highly Oscillatory Integrals with Bessel Function Kernels

open access: yesMathematics
In this paper, we investigate efficient numerical methods for highly oscillatory integrals with Bessel function kernels over finite and infinite domains. Initially, we decompose the two types of integrals into the sum of two integrals.

General Master Theorems of Integrals with Applications

open access: yesMathematics, 2022
Many formulas of improper integrals are shown every day and need to be solved in different areas of science and engineering. Some of them can be solved, and others require approximate solutions or computer software.
