چکیده
A class of nonlinear Fokker–Planck equations with nonlocal interactions may include many important cases, such as porous medium external potentials and aggregation–diffusion models. The trajectory equation the Fokker–Plank can be derived based on an energetic variational approach. structure‐preserving numerical scheme that is mass conservative, energy stable, uniquely solvable, positivity preserving at a theoretical level has also been designed in previous work. Moreover, shown to satisfy discrete dissipation law preserve steady states observed second order accurate space first‐order time various experiments. In this work, we give rigorous convergence analysis for highly scheme. careful higher asymptotic expansion needed handle nature equation. addition, two step error estimates (a rough estimate refined estimate) are necessary proof. Different from standard estimate, performed control term. few results presented verify optimal preservation equilibria.

New iterative methods with seventh-order convergence for solving nonlinear equations
In this paper, seventh-order iterative methods for the solution ofnonlinear equations are presented. The new iterative methods are developed byusing weight function method and using an approximation for the last derivative,which reduces the required number of functional evaluations per step. Severalexamples are given to illustrate the eciency and the performance of the newiterative methods.

متن کاملConvergence analysis of product integration method for nonlinear weakly singular Volterra-Fredholm integral equations
In this paper, we studied the numerical solution of nonlinear weakly singular Volterra-Fredholm integral equations by using the product integration method. Also, we shall study the convergence behavior of a fully discrete version of a product integration method for numerical solution of the nonlinear Volterra-Fredholm integral equations. The reliability and efficiency of the proposed scheme are...
متن کاملNumerical Solution of Some Nonlocal, Nonlinear Dispersive Wave Equations
We use a spectral method to solve numerically two nonlocal, nonlinear, dispersive, integrable wave equations, the Benjamin-Ono and the Intermediate Long Wave equations. The proposed numerical method is able to capture well the dynamics of the solutions; we use it to investigate the behaviour of solitary wave solutions of the equations with special attention to those, among the properties usuall...
