Abstract
A new proof based on F. Browder’s ideology is given for the theorem on the approximation of weak solutions of the Laplace equation in a bounded domain \(\Omega \subset {{\mathbb{R}}^{n}}\), \(n \geqslant 2\), with a connected Lipschitz boundary by harmonic polynomials in the Lebesgue space \({{L}_{p}}(\Omega )\) and the Sobolev space \(W_{p}^{1}(\Omega )\).

摘要
基于F. Browder意识形态的新证明为定理\(\ Omega \ subset {{\ mathbb {R}} ^ {n}} \)中的Laplace方程的弱解的逼近定理给出,\(n \ geqslant 2 \),在Lebesgue空间\({{L} _ {p}}(\ Omega)\)和Sobolev空间\(W_ {p} ^ { 1}(\ Omega)\)。
