Abstract

The flows of phase trajectories in cosmological models based on the asymmetric scalar Higgs doublet are investigated. It is shown that phase flows tend to split into several diverging flows. In this case, initially close phase trajectories can diverge significantly over time, which indicates the instability of the model with respect to finite perturbations.

不对称标量希格斯双重态宇宙演化完整模型中的相流

研究了基于非对称标量希格斯双重态的宇宙学模型中相轨迹的流动。结果表明，相流有分裂成若干个分散流的趋势。在这种情况下，最初接近的相轨迹可以随着时间的推移而显著发散，这表明模型相对于有限扰动的不稳定性。

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
