Title: Method of Moving Frames

Speaker: Chong-Kyu Han

ABSTRACT

The method of moving frames has been largely developed by Elie Cartan (1869-195

1) and is now a fundamental tool of differential geometry. In this talk I will explain

the basic notions and how this method naturally arose in early 20th century. Cartan's me

thod of moving frames and its variants have many applications. Briefly, I will present a

few of the applications including holomorphic equivalence of real hypersurfaces in comp

lex spaces and solvability of overdetermined pde systems.
