AI总结:

针对包含从0到t和从t到无穷两个积分项的非线性积分方程组,提出数值方法并证明收敛性及收敛速率,同时证明有限截断逼近无限维系统解的结果。

摘要:

我们开发了一种数值方法,用于求解包含两个积分项的非线性积分方程组:在当前时间t,一个积分从0到t,另一个不同的积分从t到无穷。我们证明了该方法的收敛性和收敛速率。离散化导致一个无限维非线性系统,我们还证明了用有限截断的解逼近无限维系统解的结果。

英文摘要:

We develop a numerical method for solving a system of nonlinear integral equations involving two integral terms: at the current time t, one integral is taken from 0 to t, and a different integral is taken from t to infinity. We prove the convergence and the rate of convergence of our method. The discretization results in an infinite-dimensional nonlinear system, and we also prove results on the approximation of the solution of the infinite-dimensional system by solution of finite truncations.
