On some questions of the weak solutions of evolution equations for magnetohydrodynamic type
Damázio, Pedro D.

We prove that the weak solution of the equations for magneto-hydrodynamic type posses fractional derivatives in time of any order less that 1/2 if n = 2 and that it is true conditionally in the three and four-dimensional cases. Also, we give some results of uniqueness of weak solutions similar to the Navier-Stokes equations for n > 3. Thus, we reach the same level of knoweledge as the one in the case of the classical Navier-Stokes.
