求解Neumann外问题有限元与边界积分方法的逼近分析

The Approximations for an Exterior Neumann Problem by Finite Element and Boundary integral Methods

本文用有限元与边界积分方法，给出Neumann外问题的一种新的数值方法，获得了此法的变分方程并证明其适定性,导出逼近解的渐近误差估计．

In thes paper,we present a new numerical method for solving the Neurnann problem with exterior domain.The technique consists of coupling of the abate element and boundary integral methods.The discrete variational formulation and well-posedness of the coupling method are obtained.The asylnptotic estimates for the appropriation solution are provided.
