Convergence of the Laplace and the alternative multipole expansion approximation series for the Coulomb potential

open access: yesScientific Reports, 2023
Multipole expansion is a powerful technique used in many-body physics to solve dynamical problems involving correlated interactions between constituent particles.

An extensive note on various fractional-order type operators and some of their effects to certain holomorphic functions

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2022
The aim of this paper is to present background information in relation with some fractional-order type operators in the complex plane, which is designed by the fractional-order derivative operator(s).

The contact process in heterogeneous and weakly-disordered systems [PDF]

open access: yes, 2006
The critical behavior of the contact process (CP) in heterogeneous periodic and weakly-disordered environments is investigated using the supercritical series expansion and Monte Carlo (MC) simulations. Phase-separation lines and critical exponents $\beta$

A Generalized Series Expansion of the Arctangent Function Based on the Enhanced Midpoint Integration

open access: yesAppliedMath, 2023
In this work, we derive a generalized series expansion of the acrtangent function by using the enhanced midpoint integration (EMI). Algorithmic implementation of the generalized series expansion utilizes a two-step iteration without surd or complex ...

Short-time fluctuations of displacements and work [PDF]

open access: yes, 2006
A recent theorem giving the initial behavior of very short-time fluctuations of particle displacements in classical many-body systems is discussed. It has applications to equilibrium and non-equilibrium systems, one of which is a series expansion of the ...

Expansion of multiple series in infinite diagonals

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013
In this paper a method of summation of double absolutely convergent numerical series was obtained. This method was named the expansion of double numerical series in infinite diagonals.

An approach for one dimensional periodic arbitrary lithography based on Fourier series

open access: yesEngineering Science and Technology, an International Journal, 2021
In interference lithography, 1-dimensional (1D) Fourier series expansion (FSE) technique can be used to create 1D periodic arbitrary patterns. Since the energy of electric field can change the solubility of photoresist, the required electric field ...

SIGMOIDAL-TYPE SERIES EXPANSION [PDF]

open access: yesThe ANZIAM Journal, 2008
Abstract In this paper we introduce a set of orthonormal functions, $\{\phi _n^{[r]}\}_{n=1}^{\infty }$ , where ϕ n [r] is composed of a sine function and a sigmoidal transformation γ r of order r>0. Based on the proposed functions ϕ n [r] named by sigmoidal sine functions, we consider a series ...

Series expansion for a stochastic sandpile

open access: yes, 2003
Using operator algebra, we extend the series for the activity density in a one-dimensional stochastic sandpile with fixed particle density p, the first terms of which were obtained via perturbation theory [R. Dickman and R. Vidigal, J. Phys.
