Title: Polygon spaces and spin action

Abstract: In this talk, we discuss the geometry of the polygons in Euclidean spaces. We explain fundamental issues of chamber structures of polygon spaces according to moment maps and related polytopes, and introduce an approach with spin action to characterize polygons in 5-dimensional Euclidean space. This is a joint with Eunjeong Lee.
