Concentration Of Laplace Eigenfunctions And Stabilization Of Weakly Damped Wave Equation

N. BurqClaude Zuily

文献摘要

In this article, we prove some universal bounds on the speed of concentration on small (frequency-dependent) neighborhoods of submanifolds of L 2-norms of quasi modes for Laplace operators on compact manifolds. We deduce new results on the rate of decay of weakly damped wave equations. R{'e}sum{'e}.
