Title |
Simplicial volume and locally symmetric spaces |
Abstract |
The notion of simplicial volume was introduced by Gromov and Thurston in the early 1980’s, and measures how efficiently a manifold can be “triangulated over the reals”. I’ll explain various results that follow from positivity of this invariant. I will also outline the proof (joint with B. Schmidt) of the following conjecture of Gromov: every closed locally symmetric space of non-compact type has positive simplicial volume. |
