Strichartz and Spectral Projection Estimates on Asymptotically Conic Manifolds

Zhexing Zhang

We prove the lossless unit interval Strichartz theorem on asymptotically conic surfaces, assuming that a large enough neighborhood of its trapped set has negative curvature. We als…

Structure constants of Peterson Schubert calculus

Tao Gui, Yuqi Jia, Xinkai Yu +2

We give an explicit, positive, and type-uniform formula for all equivariant structure constants of the Peterson Schubert calculus in arbitrary Lie types, using only the Cartan matr…

Lossless Strichartz and spectral projection estimates on unbounded manifolds

Xiaoqi Huang, Christopher D. Sogge, Zhongkai Tao +1

We prove new lossless Strichartz and spectral projection estimates on asymptotically hyperbolic surfaces, and, in particular, on all convex cocompact hyperbolic surfaces. In order…

Spectral projection estimates restricted to uniformly embedded submanifolds

Zhexing Zhang

Let $M$ be a manifold with nonpositive sectional curvature and bounded geometry, and let $I^£$ be a uniformly embedded submanifold of $M .$ We estimate the $L^{2} (M) \to L^{q} (I^£)$ norm o…
