Seminar on Ricci flow

Seminar on Ricci flow

Semester
SoSe 2017

Lecturer

Type of course (Veranstaltungsart)
Seminar

Contents
In this seminar we will study the Ricci-flow in arbitrary dimensions. The Ricci flow in dimension 3 provides the geometrisation of compact oriented 3-manifolds in the sense of Thurston. This is a decomposition in elementary pieces. The Poincare conjecture is a special case. One talk of the seminar will sketch this program. Other topics are shorttime existence and uniqueness of the flow, the neckpinch and curvature evolution. The goal is to understand the behavior of the flow until the blowup in singularities and the entropy formula. However, it is not realistic to give a full proof of the geometrisation within this seminar. Instead our aim is to acquire an overview over the central parts of the proof.
