摘要

本文在二维NT-DFIDE中引入了一类二阶奇异核的非线性Fredholm积分微分方程。并对该方程进行了数值研究。证明了该方程唯一解的存在性。采用Toeplitz矩阵法(TMM)和product Nystrom法(PNM)对nt - dfid进行了数值计算。给出的应用表明了这些方法的有效性。

Two-Dimensional Fredholm Integro-Differential Equation with Singular Kernel and Its Numerical Solutions
In this paper, we introduce the nonlinear Fredholm integro-differential equation of the second kind with singular kernel in two-dimensional NT-DFIDE. Furthermore, we study this new equation numerically. The existence of a unique solution of the equation is proved. The numerical results of NT-DFIDE are obtained by the following methods: Toeplitz matrix method (TMM) and product Nystrom method (PNM). The given applications showed the efficiency of these methods.
