Abstract

We discuss a variable order wavelet method for boundary integral formulations of elliptic boundary value problems. The wavelet basis functions are transformations of standard nodal basis functions and have a variable number of vanishing moments. For integral equations of the second kind we will show that the non-standard form can be compressed to contain only O(N) non-vanishing entries while retaining the asymptotic converge of the full Galerkin scheme, where N is the number of degrees of freedom in the discretization.
一种非标准形式层电位稀疏表示的变阶小波方法
讨论了椭圆型边值问题边界积分公式的变阶小波变换方法。小波基函数是标准节点基函数的变换,具有可变数量的消失矩。对于第二类积分方程,我们将证明非标准形式可以被压缩为只包含O(N)个非消失项,同时保持全伽辽金格式的渐近收敛,其中N是离散化中的自由度数。
