【摘要】 研究了一般线性方法(GL方法)关于一类刚性延迟系统的D-收敛性,通过拓展刚性常微分方程数值方法的B-收敛结果,一些新的判定刚性延迟系统数值方法D-收敛阶的准则被导出。在文末,数值例子阐明所获理论结果。更多还原

【Abstract】 D-convergence of general linear (GL) methods was studied for a class of stiff delay systems. By extending the B-convergence results of numerical methods for stiff ordinary differential equations, some new criteria to determine D-covergence order of numerical methods for stiff delay systems were derived. A numerical example was to illustrate the obtained theoretical results.更多还原
