Query: Resolvent estimates for wave operators in Lipschitz domains   In this paper we study the resolvent of wave operators on open and bounded
Lipschitz domains of $\mathbb{R}^N$ with Dirichlet or Neumann boundary
conditions. We give results on existence and estimates of the resolvent for the
real and complex cases.
