Lie symmetry and μ-symmetry methods for nonlinear generalized Camassa–Holm equation

Jafari, H.; Goodarzi, K.; Khorshidi, M.; Parvaneh, V.; Hammouch, Z. (2021-07-08)

Abstract In this paper, a Lie symmetry method is used for the nonlinear generalized Camassa–Holm equation and as a result reduction of the order and computing the conservation laws are presented. Furthermore, ...
A new numerical method to solve pantograph delay differential equations with convergence analysis

Jafari, H.; Mahmoudi, M.; Noori Skandari, M. H. (2021-02-25)

The main aim presented in this article is to provide an efficient transferred Legendre pseudospectral method for solving pantograph delay differential equations. At the first step, we transform the problem into a continuous-time ...
Operational matrices based on the shifted fifth-kind Chebyshev polynomials for solving nonlinear variable order integro-differential equations

Jafari, H.; Nemati, S.; Ganji, R. M. (2021-10-02)

Abstract In this research, we study a general class of variable order integro-differential equations (VO-IDEs). We propose a numerical scheme based on the shifted fifth-kind Chebyshev polynomials (SFKCPs). ...
