Uniform Hölder Bounds for Competition Systems with Strong Interaction on a Subdomain
《Journal of Applied Mathematics and Physics》2023年第6期1525-1540,共16页Jiahao Ni Shan Zhang 
We prove the uniform Hölder bounds of solutions to a singularly perturbed elliptic system arising in competing models in population dynamics. In this system, two species compete to some extent throughout the whole dom...

An Efficient Particle Subdomain Quadrature Scheme for the Material Point Method
《Acta Mechanica Solida Sinica》2021年第2期274-285,共12页Zheng Sun Xiaornin Zhou 
supported by the National Natural Science Foundation of China(11902127);the Natural Science Foundation of Jiangxi Province of China(20192BAB212010);Education Department of Jiangxi Province of China(GJJ180499).
The material point method(MPM)has been proved to be an effective numerical method for large deformation problems.However,the MPM suffers from the cell crossing error as that the material particles are used to represen...

Subdomain Chebyshev Spectral Method for 2D and 3D Numerical Differentiations in a Curved Coordinate System
《Journal of Applied Mathematics and Physics》2015年第3期358-370,共13页Bing Zhou Graham Heinson Aixa Rivera-Rios 
A new numerical approach, called the “subdomain Chebyshev spectral method” is presented for calculation of the spatial derivatives in a curved coordinate system, which may be employed for numerical solutions of part...

Time-Spectral Solution of Initial-Value Problems—Subdomain Approach
《American Journal of Computational Mathematics》2012年第2期72-81,共10页Jan Scheffel Ahmed A. Mirza 
Temporal and spatial subdomain techniques are proposed for a time-spectral method for solution of initial-value problems. The spectral method, called the generalised weighted residual method (GWRM), is a generalisatio...

RAPID EXACT CONTROLLABILITY OF THE WAVE EQUATION BY CONTROLS DISTRIBUTED ON A TIME-VARIANT SUBDOMAIN被引量：1
《Chinese Annals of Mathematics,Series B》1999年第1期65-76,共12页LIUKANGSHENG YONGJIONGMIN 
Consider the wave equation with distributed controls supported on a subdomain, calledcontrol subdomain, which is allowed to be variant in time. For any prescribed time duration,the authors work out a scheme for changi...

A PRECONDITIONER DETERMINED BY A SUBDOMAIN COVERING THE INTERFACE
《Journal of Computational Mathematics》1994年第1期71-77,共7页Zhang Sheng(Computing Center, Academia Sinica, Beijing, China) 
A method for construction of a preconditioner for the capacitance matrix on the interface is described. The preconditioner is determined by a subdomain covering the interface, and the condition number of the precondit...
