A human property (T) proof for high-rank
Martin Nitsche
Existing property (T) proofs for , , rely crucially on extensive computer calculations. We give a new proof that has property (T) for all but finitely…
Arithmetic Monodromy in Sp(2n)
Jitendra Bajpai, Daniele Dona, Martin Nitsche
Based on a result of Singh--Venkataramana, Bajpai--Dona--Singh--Singh gave a criterion for a discrete Zariski-dense subgroup of Sp(2n,Z) to be a lattice. We adapt this criterion so…
Higher-degree bounded cohomology of transformation groups
Martin Nitsche
For a compact Riemannian manifold Brandenbursky and Marcinkowski constructed a transfer map and used it to show that for certain …
Computer proofs for Property (T), and SDP duality
Martin Nitsche
We show that the semidefinite programs involved in the computer proofs for Kazhdan's property (T) satisfy strong duality and that the dual programs have a geometric interpretation…
Universal solvability of group equations
Martin Nitsche, Andreas Thom
We give a new criterion for solvability of group equations, providing proofs of various generalizations of the Kervaire-Laudenbach conjecture for Connes-embeddable groups.
