论文摘要
我们研究了带有光滑边界的R d，d $ \ ge $ 2中有界域中弹性的固定线性方程的Dirichlet到Neumann图。我们表明，可以通过矩阵值符号在边界上的伪差操作员近似它，我们通过单位矩阵计算主符号模量。
We study the Dirichlet-to-Neumann map for the stationary linear equation of elasticity in a bounded domain in R d , d $\ge$ 2, with smooth boundary. We show that it can be approximated by a pseudodifferential operator on the boundary with a matrix-valued symbol and we compute the principal symbol modulo conjugation by unitary matrices.
