摘要：

We derive uniform weighted L-2 and Morrey-Campanato type estimates for Helmholtz equations in a medium with a variable index which is not necessarily constant at infinity. Our technique is based on a multiplier method with appropriate weights which generalize those of Morawetz for the wave equation. We also extend our method to the wave equation.
