摘要：
In this paper, we consider an initial-boundary value problem for the equations of a fluid spherical model of neutron star considered by Lattimer et al. We establish the global existence and regularity of the spherically symmetric solutions in H-i (i = 1, 2, 4) of this fluid model. These results improve and generalize the results of Ducomet and Necasova (Ann. Univ. Ferrara 55(1):153-193, 2009).
