On the growth of -invariants for sequences of lattices in Lie groups
Miklos Abert, Nicolas Bergeron, Ian Biringer +4
We study the asymptotic behaviour of Betti numbers, twisted torsion and other spectral invariants of sequences of locally symmetric spaces. Our main results are uniform versions of…

On the number of finite subgroups of a lattice
Iddo Samet
We show that the number of conjugacy classes of maximal finite subgroups of a lattice in a semisimple Lie group is linearly bounded by the covolume of the lattice. Moreover, for hi…
