Such generators have been operated as sources for … WebIn this paper, we study the energy equality and the uniqueness of weak solutions to the MHD equations in the critical space L∞(0,T;Ln(Ω)). We prove that if the velocity u belongs to the critical space L∞(0,T;Ln(Ω)), the energy equality holds. On the basis of the energy equality, we further prove that the weak solution to the MHD equations is unique.
