Fictitious Time Integration Method of Fundamental Solutions with Chebyshev Polynomials for Solving Poisson-type Nonlinear PDEs [PDF]

open access: yesComputer Modeling in Engineering & Sciences, 2010
The fictitious time integration method (FTIM) previously developed by Liu and Atluri (2008a) is combined with the method of fundamental solutions and the Chebyshev polynomials to solve Poisson-type nonlinear PDEs. The method of fundamental solutions with Chebyshev polynomials (MFS-CP) is an exponentially-convergent meshless numerical method which is ...

On Mean Value formulas for solutions to second order linear PDEs [PDF]

open access: yes, 2021
In this paper we give a general proof of Mean Value formulas for solutions to second order linear PDEs, only based on the local properties of their fundamental solution Gamma.

On the crest factor and its relevance in detecting turbulent behaviour in solutions of partial differential equations [PDF]

open access: yes, 2022
In this work we investigate the connection between two fundamental features of solutions of partial differential equations (PDEs), namely the crest factor and the length scale associated to each solution.

Free convection channel flow of couple stress casson fluid: A fractional model using Fourier’s and Fick’s laws

open access: yesFrontiers in Physics, 2023
Fractional calculus is a branch of mathematics that develops from the usual definitions of calculus integral and derivative operators, just as fractional exponents emerge from integer exponents.

Fundamental solutions, transition densities and the integration of Lie symmetries [PDF]

open access: yes, 2009
In this paper we present some new applications of Lie symmetry analysis to problems in stochastic calculus. The major focus is on using Lie symmetries of parabolic PDEs to obtain fundamental solutions and transition densities.

Domain decomposition methods with fundamental solutions for Helmholtz problems with discontinuous source terms [PDF]

open access: yes, 2018
The direct application of the classical method of fundamental solutions (MFS) is restricted to homogeneous linear partial differential equations (PDEs).

Probabilistic solutions of fractional differential and partial differential equations and their Monte Carlo simulations [PDF]

open access: yes, 2022
The work in this paper is four-fold. Firstly, we introduce an alternative approach to solve fractional ordinary differential equations as an expected value of a random time process.
