| Abstract： |
Note that some classic fluid dynamical systems such as the Navier-Stokes
equations, Magnetohydrodynamics (MHD for short), Boussinesq equations and etc., are
observably different from each other but obey some energy inequalities of the similar type.
In this paper, the authors attempt to axiomatize the extending mechanism of solutions to
these systems, merely starting from several basic axiomatized conditions such as the local
existence, joint property of solutions and some energy inequalities. The results established
have nothing to do with the concrete forms of the systems and, thus, give the extending
mechanisms in a unified way to all systems obeying the axiomatized conditions. The key
tools are several new multiplicative interpolation inequalities of Besov type, which have
their own interests. |
