A note on helicity conservation for compressible Euler equations in a bounded domain with vacuum (2505.20080v2)

Published 26 May 2025 in math.AP

Abstract: In this paper, we consider the helicity conservation of weak solutions for the compressible Euler equations in a bounded domain with general pressure law and vacuum. We deduce a sufficient condition for a weak solution conserving the helicity based on the interior Besov-VMO type regularity, the continuous conditions for velocity and vorticity near the boundary, and some regularities for density near vacuum.
