Stabilities for Nonisentropic Euler-Poisson Equations

Abstract EN

We establish the stabilities and blowup results for the nonisentropic Euler-Poisson equations by the energy method.

By analysing the second inertia, we show that the classical solutions of the system with attractive forces blow up in finite time in some special dimensions when the energy is negative.

Moreover, we obtain the stabilities results for the system in the cases of attractive and repulsive forces.
