| Summary: | 碩士 === 國立臺灣師範大學 === 物理學系 === 105 === Inflationary theory is the prime candidate for solving the flatness, horizon, monopole problem that are encountered in the standard Big Bang, it also provides a way for seeding the large scale structure that we see today. In this thesis we study the behavior of the tensor to scalar ratio in the context of warm inflation where there is a dissipation present due to the interaction between the inflaton and other fields which are neglected in the standard cold inflation. We will also provide another approach on determining the observables during inflation by solving the evolution of the quantities in question. The tensor to scalar ratio can be approximated using the slow-roll parameters, this in turn can be used to check the authenticity of the approach taken. We fix the number of e-folding to be 60 before the end of inflation.
