Local and global well-posedness for the extended Schrödinger-Benjamin-Ono system
Puti Dai, Justin Forlano
We study the well-posedness problem for the extended Schrödinger-Benjamin-Ono system (eSBO) on the real line. This system couples a Schrödinger field with a Benjamin-Ono type f…

Sharp Strichartz estimate for the 1D periodic Schrödinger equation
Puti Dai, Zihua Guo
We prove the following estimate \[ \|{e^{it\partial_x^2}f}\|_{L_{(t,x)\in \mathbb{T}^2}^6}\leq C (\log N)^{1/6} \|f\|_{L^2_x(\mathbb{T})}, \] assuming $\mbox{supp} (\hat f)\subset…
