"We consider the Cauchy problem for the equations of spherically symmetric motions in R-3, of a selfgravitating barotropic gas, with possibly non monotone pressure law, in two different situations: in the first one we suppose that the viscosities mu(rho), and lambda(rho) are density-dependent and satisfy the Bresch-Desjardins condition, in the second one we consider constant densities. In the two cases, we prove that the problem admits a global weak solution, provided that the polytropic index gamma satisfy gamma > 1."@en . "RIV/67985840:_____/11:00360534" . "Vasseur, A." . . .
