Then, based on above review, we propose an analytical tachyon inflation model driven by scalar field with bom - infeld - type lagrangian. we find it ' s an analytical model if we choose an exponential potential. we compute it ' s power spectrum and find that it can explain the evolution of universe
如果將勢選擇為指數勢，模型變成精確可解的，本文找到了一個精確解析的宇宙暴漲解並利用該解計算了cmb譜，發現這個解可以用來解釋宇宙的演化。 -
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
