Abstract
The resonances of the Laplacian on perturbations of half-spaces of dimensio ns greater than or equal to two, with either Dirichlet or Neumann boundary conditions, are studied. An upper bound for the resonance counting function is proven. If the domain has an elliptic, nondegenerate, nonglancing perio dic billiard trajectory, it is shown that there exists a sequence of resona nces that converge to the real axis.
