N. Burq, Claude Zuily

摘要:

- 本文证明了紧致流形上Laplace算子在拟模的L2-范数子流形的小(频率相关)邻域上集中速度的一些普遍界.我们推出了弱阻尼波动方程衰减率的新结果。R{é}sum{é}.

英文摘要:

- 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{é}sum{é}.
