PhD seminar: Dehn twists and the mapping class group of surfaces
- Location: Ångströmlaboratoriet, Lägerhyddsvägen 1
- Lecturer: Sebastian Pöder

It is a theorem of Lickorish that the mapping class group of a closed, oriented surface is generated by Dehn twists. In the talk we will define these notions and sketch Lickorish's 1961 proof.
