紧流形上从半经典的Escherichartz估计到一致$L^p$预解式估计

From semiclassical Strichartz estimates to uniform $L^p$ resolvent estimates on compact manifolds

Nicolas Burq, David Dos Santos Ferreira, Katya Krupchyk

摘要:

我们证明了平稳阻尼波算子的一致$L^p$预解估计。无边界紧致光滑黎曼流形上Laplace算子的一致$L^p$预解估计首先由Dos Santos Ferreira-Kenig-Salo建立,并由Bourgain-Shao-Sogge-Yao进一步推广.在这里,我们提供了一个替代的证明依赖于半经典Eschenhartz估计的技术。这种方法也使我们能够处理非自伴扰动的拉普拉斯算子和嵌入非常自然的半经典谱分析框架。

英文摘要:

We prove uniform $L^p$ resolvent estimates for the stationary damped wave operator. The uniform $L^p$ resolvent estimates for the Laplace operator on a compact smooth Riemannian manifold without boundary were first established by Dos Santos Ferreira-Kenig-Salo and advanced further by Bourgain-Shao-Sogge-Yao. Here we provide an alternative proof relying on the techniques of semiclassical Strichartz estimates. This approach allows us also to handle non-self-adjoint perturbations of the Laplacian and embeds very naturally in the semiclassical spectral analysis framework.
