Pointwise estimates for the fundamental solutions of higher order Schrödinger equations in odd dimensions II: high dimensional case

Han Cheng, Shanlin Huang, Tianxiao Huang +1

In this paper, for any odd $n$ and any integer $m\ge 1$ with $n>4m$, we study the fundamental solution of the higher order Schrödinger equation \begin{equation*} \mathrm{i}\partial…
