恒星基态的两种粒子的P-Fermi模型

A Two Species Thomas-Fermi Model for Stellar Ground States

Parker Hund

摘要:

本文给出了一个非相对论动能的自引力非旋转带电体的B-Fermi型双流体模型的能量泛函。我们证明,在带正电和带负电的粒子总数的某些条件下,存在最小值,并且两种流体都具有紧支持。我们证明了同样的结果为特殊的相对论性动能,假设进一步的条件的总粒子数。在非相对论性动能的情况下,我们进一步证明了极小的唯一性,以及目前的结果有关的一般形状的极小粒子的总数。

英文摘要:

We present an energy functional for a Thomas-Fermi type two-fluid model of a self-gravitating non-rotating charged body, with a non-relativistic kinetic energy. We prove that, under certain conditions on the total number of positively charged and negatively charged particles, a minimizer exists and both fluids have compact support. We prove the same result for special relativistic kinetic energy, assuming further conditions on the total number of particles. In the non-relativistic kinetic energy case, we further prove the uniqueness of the minimizer, as well as present results relating the general shape of the minimizer to the total number of particles.
