Weak delay-dependent stability of Rosenbrock methods for neutral delay differential equations

在中立型时滞微分方程存在时滞相关渐近稳定解的条件下,研究了中立型时滞微分方程的Rosenbrock方法的弱时滞相关稳定性.基于辐角原理,给出了Rosenbrock方法的弱时滞渐近稳定性的充分条件,并通过数值例子验证理论结果的有效性.

The weak delay-dependent stability of the Rosenbrock methods for neutral delay differential equations is studied under the condition that the equations are delaydependent asymptotically stable.Based on the argument principle,a sufficient condition for the weak delay asymptotic stability of Rosenbrock methods is given.Finally,numerical examples are provided to verify the effectiveness of the theoretical results.
