A Liouville theorem for the Chern--Simons--Schr{ö}dinger equation

In this paper we prove a Liouville theorem for the Chern–Simons–Schr{ö}dinger equation. This result is consistent with the soliton resolution conjecture for initial data that does not lie in a weighted space. See [KKO22] for the soliton resolution result in a weighted space.
