$H^s$ wave front set for Schrödinger equations with sub-quadratic potential
$H^s$ wave front set for Schrödinger equations with sub-quadratic potential
The aim of this work is to study regularity of solutions of the initial value problem for the Schrӧdinger equations with sub-quadratic potential. More precisely, we determine the $H^s$ wave front sets of solutions from the behavior at infinity of the initial data by using the characterization of the $H^s$ …
