Firstly , in order to make a theoretical preparation for tachyon cosmology and d - star , we briefly review the standard hot big bang cosmology with inflation 在这个模型中,快子场作为暴涨场,即由born - infeld标量场导致宇宙暴涨。
In this master dissertation , under the fundamental frame of general relativity , we study the tachyon inflation , d - stars in the spacetime with a nonzero cosmological constant and it ' s observable effects by using some modern mathematical methods such as differential equation and qualitative analysis 本文以广义相对论作为基本理论框架,使用微分方程及其定性理论,研究了宇宙演化和结构中的两个问题,其中包括了快子暴涨,非零宇宙常数时空中的d星以及它的种种可观测效应。
This paper expounded of the connotation of causality and causal anomaly ; it is pointed out that with closed systems the existence of tcahyons is compatible within the causality requirements of the theory ofrelativity , but the possibility of experimentation with tachyons beingsuitable for signaling must be excluded 摘要本文阐述了物理学中因果性和因果反常的涵义,指出在闭合系里快子的存在可以和相对论因果性要求一致,但是适合作信号的快子实验的可能性必须被排除。
