我们考虑 nutron 星的一个一个维的连续模型,与状态的一个非单调方程由一个可压缩的 thermoviscoelastic 系统描述了由于在 particles.We 之间的原子相互作用将证明那的有效 Skyrme ,尽管有可能的使动摇,压力影响,它是非单调并且不总是积极,粘性和足够的热驱散的存在为我们的模型与一个混合免费边界问题在 H4 描述答案的全球存在。
We consider a one-dimensional continuous model of nutron star, described by a compressible thermoviscoelastic system with a non-monotone equation of state, due to the effective Skyrme nuclear interaction between particles. We will prove that, despite a possible destabilizing influence of the pressure, which is non-monotone and not always positive, the presence of viscosity and a sufficient thermal dissipation describe the global existence of solutions in H^4 with a mixed free boundary problem for our model.
