Boundary epsilon regularity for incompressible Navier--Stokes equations via weak-strong uniqueness

Siran Li · 2026

We show that finite-energy weak solutions to the incompressible Navier--Stokes equations on a three-dimensional bounded smooth domain are regular up to the boundary, provided that the $L^4_tL^4_x$-nor…
