AI总结:

本文研究了不同类型的弱奇异Volterra积分方程,讨论了一维和多维方程的最优精度数值方法构造,并评估了Babenko和Kolmogorov紧集的n-宽度,最后给出了二维Volterra方程的数值示例。

摘要:

本文考虑了不同类型的弱奇异Volterra积分方程。讨论了一维和多维方程的最优精度数值方法的构造。由于这个问题与最优逼近问题密切相关,因此评估了从某些函数类中紧集的Babenko和Kolmogorov $n-\$宽度。最后,我们为二维Volterra方程提供了某些数值示例。

英文摘要:

Weakly singular Volterra integral equations of the different types are considered. The construction of accuracy-optimal numerical methods for one-dimensional and multidimensional equations is discussed. Since this question is closely related with the optimal approximation problem, the orders of the Babenko and Kolmogorov \(n-\)widths of compact sets from some classes of functions have been evaluated. In conclusion we adduce some numerical illustrations for 2-D Volterra equations.
