Sharp bilinear eigenfunction estimate, -type Strichartz estimate, and energy-critical NLS

Yangkendi Deng, Yunfeng Zhang, Zehua Zhao

We establish sharp bilinear eigenfunction estimates for the Laplace-Beltrami operator on the standard three-sphere , eliminating the logarithmic loss that has persist…

On bilinear Strichartz estimates on waveguides with applications

Yangkendi Deng, Chenjie Fan, Kailong Yang +2

We study local-in-time and global-in-time bilinear Strichartz estimates for the Schrödinger equation on waveguides. As applications, we apply those estimates to study global well-p…

On a bilinear restriction estimate for Schrödinger equations on 2D waveguide

Yangkendi Deng

In this article, we prove a bilinear estimate for Schrödinger equations on 2d waveguide, . We hope it may be of use in the further study of concentrati…
