The most symmetric Heegaard splittings
Topics on hyperbolic geometry
Date: from June 20 to July 20
Venue: Lecture Hall, Institute for Advanced Study in Mathematics, No.7 teaching building
[ IASM visitors plan to organize an irregular seminar from June 20 to July 20. We will arrange about eight 1.5-hour introductory talks, on recent topics in hyperbolic geometry (and low-dimensional topology). The purpose of this seminar is to enhance communication and learn advances in the area. ]
Upcoming Seminar：
Date: | July 14 Wed. 3:00pm -- 4:30 pm |
Speaker: | Chao Wang (East China Normal University) |
Title: | The most symmetric Heegaard splittings |
Abstract: | It is known that in the orientable category the maximum order of finite group actions on genus g>1 Heegaard splittings is 12(g-1). We will give a classification of the actions realizing this bound in the meaning of Thurston’s geometrization of 3-orbifolds. As a useful tool, alternating trivalent graphs and its relation with geometric 3-orbifolds will also be introduced. |
