AI总结:
本文首次证明了在解析边界区域上随机选取离散点时,2D Poisson 方程的薄板样条非对称 Kansa 配置矩阵几乎必然非奇异,为解决 PDE 的 Kansa 配置唯一可解性充分条件存在性这一未解问题迈出了第一步。
摘要:
PDE 的 Kansa 非对称配置唯一可解性充分条件存在性仍是未解问题。本文迈出第一步,证明当离散点在解析边界区域上随机选取时,2D Poisson 方程的薄板样条非对称配置矩阵几乎必然非奇异。
英文摘要:
Existence of sufficient conditions for unisolvence of Kansa unsymmetric collocation for PDEs is still an open problem. In this paper we make a first step in this direction, proving that unsymmetric collocation matrices with Thin-Plate Splines for the 2D Poisson equation are almost surely nonsingular, when the discretization points are chosen randomly on domains with analytic boundary.
