非对称散度型方程边值问题的非唯一解

Non unique solutions to boundary value problems for non symmetric divergence form equations

Andreas Axelsson

摘要:

本文给出了一类具有跳跃间断的非对称系数的散度型方程的Dirichlet和Neumann边值问题在上半平面上的显式解.当系数充分非对称时,用边界方程法和Lax-Milgram方法构造解可能得到两种不同的解。

英文摘要:

We calculate explicitly solutions to the Dirichlet and Neumann boundary value problems in the upper half plane, for a family of divergence form equations with non symmetric coefficients with a jump discontinuity. It is shown that the boundary equation method and the Lax--Milgram method for constructing solutions may give two different solutions when the coefficients are sufficiently non symmetric.
