Ice-Creams and Wedge Graphs
Eyal Ackerman, Tsachik Gelander, Rom Pinchasi
What is the minimum angle such that given any set of -directional antennas (that is, antennas each of which can communicate along a wedge of angle ), one can always ass…
On the growth of Betti numbers of locally symmetric spaces
Miklos Abert, Nicolas Bergeron, Ian Biringer +4
We announce new results concerning the asymptotic behavior of the Betti numbers of higher rank locally symmetric spaces as their volumes tend to infinity. Our main theorem is a uni…
The dynamics of Aut(F_n) on redundant representations
Tsachik Gelander, Yair Minsky
We study some dynamical properties of the canonical Aut(F_n)-action on the space R_n(G) of redundant representations of the free group F_n in G, where G is the group of rational po…
Volume vs. rank of lattices
Tsachik Gelander
We show the rank (i.e. minimal size of a generating set) of lattices cannot grow faster than the volume.
