ABSTRACT

I will discuss of a joint research with Silvia CAPRINO (Roma 2) and Guido CAVALLARO (Roma 1) We study a mathematical model in which we defend by a magnetic shield a spaceship from the solar wind of charged particles. We describe the particles of the wind via a Vlasov-Poisson system, the spaceship as a torus and the magnetic shield via a magnetic field that becomes infinite on the border of the torus. We prove the existence and uniqueness of the solution and we show that no particle enter in the torus. Moreover we discuss possible generalizations.
