Title: Supergravity cosmology

Abstract:

Quantization of gravity is one of the issues in theoretical physics. Quantized Einstein gravity has a problem of non-renormalizability, which indicates the necessity of extending Einstein gravity. Supergravity is one of the possible extension of GR, which improve the UV property of gravity. I will explain what is supergravity and the status of quantized supergravity.
I will also discuss the cosmological application of supergravity. In particular, I will show that (maximal) supergravity may be related to the class of inflation models consistent with the latest CMB observations.
