$L^2$ Schrödinger maximal estimates associated with finite type phases in ${\mathbb{R}}^2$

Zhuoran Li, Junyan Zhao, Tengfei Zhao

In this paper, we establish Schrödinger maximal estimates associated with the finite type phases \begin{equation*} ϕ(ξ_1,ξ_2):=ξ^m_1+ξ^m_2,\;(ξ_1,ξ_2)\in [0,1]^2, \end{equation*} w…
