Tóm tắt: Jordan curve theorem states that any simple closed curve in the plane separates the plane into two regions. In addition, by Schoenflies theorem, these two regions are homeomorphic to the inside and outside of a standard circle in the plane. In this talk, we will give a definable version of this (Schoenflies) theorem. (joint work with Nguyễn Xuân Việt Nhân).
