A local energy estimate for 2-dimensional Dirichlet wave equations

Kellan Hepditch and Jason Metcalfe

Vol. 16 (2023), No. 3, 483–492
Abstract

We examine a variant of the integrated local energy estimate for (1+2)-dimensional Dirichlet wave equations exterior to star-shaped obstacles. The classical bound on the solution, rather than the derivative, is not typically available in two spatial dimensions. Using an argument inspired by the rp-weighted method of Dafermos and Rodnianski and taking advantage of the Dirichlet boundary conditions allow for the recovery of such a term when the initial energy is appropriately weighted.
