Almost-minimal nonuniform lattices of higher rank
Vladimir Chernousov, Lucy Lifschitz, Dave Witte Morris
If Gamma is a nonuniform, irreducible lattice in a semisimple Lie group whose real rank is greater than 1, we show Gamma contains a subgroup that is isomorphic to a nonuniform, irr…
Bounded generation and lattices that cannot act on the line
Lucy Lifschitz, Dave Witte Morris
Let D be an irreducible lattice in a connected, semisimple Lie group G with finite center. Assume that the real rank of G is at least two, that G/D is not compact, and that G has m…
Isotropic nonarchimedean S-arithmetic groups are not left orderable
Lucy Lifschitz, Dave Morris
Let A = Z[c], where c is an irrational number whose square is rational, or let A = Z[1/r], where r > 1 is a square-free natural number. We show that no finite-index subgroup of SL(…
On automorphisms of arithmetic subgroups of unipotent groups in positive characteristic
Lucy Lifschitz, Dave Witte
Let F be a local field of positive characteristic, and let G be either a Heisenberg group over F, or a certain (nonabelian) two-dimensional unipotent group over F. If H is an arith…
