In this paper, we simplify and extend the results of [GZ] to in-clude the case in which = R3. Let [L2(R3)]3 be the Hilbert space of square integrable functions on R3 and let H[R3]3 =: H be the comple...

Global existence of weak solutions to the Navier-Stokes equation in a cylindrical domain under the slip boundary conditions and with inflow and outflow was proved. To prove the energy estimate, crucia...

It is shown by means of a simple analysis that the linearized system of transport equations for a relativistic, single component ideal gas at rest obeys the \textit{antecedence principle}, which is of...
