We prove Liouville type theorems for weak solutions of the Navier–Stokes and the Euler equations. In particular, if the pressure satisfies p∈L1(0,T;L1(RN)) with [Formula: see text] , then the corresponding velocity should be trivial, namely v=0 on RN×(0,T). In particular, this is the case when p∈L1(0,T;Hq(RN)), where Hq(RN), q∈(0,1], the Hardy space. On the other hand, we have equipartition of energy over each component, if p∈L1(0,T;L1(RN)) with [Formula: see text] . Similar results hold also for the magnetohydrodynamic equations.
