Yusuke Yamada 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. |
