# Uniqueness in a Navier-Stokes-nonlinear-Schr\"odinger model of superfluidity

@inproceedings{Jayanti2021UniquenessIA, title={Uniqueness in a Navier-Stokes-nonlinear-Schr\"odinger model of superfluidity}, author={Pranava Chaitanya Jayanti and Konstantina Trivisa}, year={2021} }

In [JT21b], the authors proved the existence of local-in-time weak solutions to a model of superfluidity. The system of governing equations was derived in [Pit59] and couples the nonlinear Schrödinger equation (NLS) and the Navier-Stokes equations (NSE). In this article, we prove two uniqueness theorems for these weak solutions. One of them is the classical weak-strong uniqueness based on a relative entropy method. The other result trades some regularity of the stronger solution for smallness…
