Abstract

Based on the mathematical model of a statistical system with scalar interaction of fermions, formulated earlier, a cosmological model based on a two-component statistical system of scalarly charged degenerate fermions interacting with an asymmetric scalar doublet of canonical and phantom scalar fields, is investigated. The asymptotic and limiting properties of the cosmological model are investigated, and it is shown that amon g all models there is a class of those with finite lifetime. The asymptotic behavior of the models near the corresponding singularities is investigated, and numerical implementations of such models are constructed.

具有非对称标量双重态的简并标量带电费米子统计系统的宇宙学演化。一、组合收费双组分制

在先前建立的费米子标量相互作用统计系统数学模型的基础上，研究了一个基于标量带电简并费米子与正则标量场和虚标量场的非对称标量双重相互作用的双组分统计系统的宇宙学模型。研究了宇宙学模型的渐近和极限性质，并证明了在所有模型中存在一类具有有限寿命的模型。研究了该模型在奇异点附近的渐近行为，并构造了该模型的数值实现。

期刊介绍： Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoplesâ€™ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
