Abstract

摘要

 

 In the flat space time, there are many things we can say about scattering amplitudes. It is tempting to think about is there similar relations also in cosmology. The talk consists of three parts. The first part is about translating the recursion relation in the flat spacetime to recursion relations among inflationary correlation functions or wave function of the universe. The second part is about the four-point KLT relations in inflation. The third part is about my ongoing work about positivity bounds in inflation. I will also talk about my thoughts in general about applying scattering amplitudes technique in cosmology.
