Query: Approximation of the elastic Dirichlet-to-Neumann map   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.
