Length functions on groups and applications to actions on Gromov hyperbolic spaces
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 12 Mon. 3:00pm -- 4:30 pm |
Speaker: | Shengkui Ye (NYU Shanghai) |
Title: | Length functions on groups and applications to actions on Gromov hyperbolic spaces |
Abstract: | In the second talk, we will continue to discuss the (rough) action of a finite-index subgroup of SL(n,R),n>2, (R is a ring of algebraic integers in a number field) on a Gromov hyperbolic space. After proving the general fixed-point property, we will discuss the actions on manifolds of pinched negative curvatures, for which more rigid results can be proved. |
