An Attempt at Axiomatization of Extending Mechanism of Solutions to the Fluid Dynamical Systems
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.
