二维模型凸区域上wave equation的Eschhartz估计的新反例

New counterexamples to Strichartz estimates for the wave equation on a 2d model convex domain

Oana Ivanovici, Gilles Lebeau, Fabrice Planchon

摘要:

我们证明了在一个模型的二维凸区域上的Eschhartz估计的范围可能会进一步限制相比,已知的反例,由于第一作者。我们的新反例族现在是建立在我们早期工作的参数构造上的。有趣的是,它至少在相空间的某些区域是尖锐的。

英文摘要:

We prove that the range of Strichartz estimates on a model 2D convex domain may be further restricted compared to the known counterexamples due to the first author. Our new family of counterexamples is now built on the parametrix construction from our earlier work. Interestingly enough, it is sharp in at least some regions of phase space.
