#### Introduction of Research

Automorphic forms, which are functions with rich symmetry, give us several number theoretic information, such as analytic continuation and functional equations of L-functions.

I study automorphic representations, which are representations consists of automorphic forms.

Arthur's classification which is a classification of automorphic representations of classical groups, is difficult to understand.

My main research theme is to study Arthur's classification using liftings of automorphic forms.
