On the energy equality for weak solutions of the 3D Navier-Stokes equations

A. Cheskidov, S. Friedlander, R. Shvydkoy

We prove that the energy equality holds for weak solutions of the 3D Navier-Stokes equations in the functional class $L^3([0,T);V^{5/6})$, where $V^{5/6}$ is the domain of the frac…
