On Quasi-homomorphisms and Commutators in the Special Linear Group over a Euclidean Ring
Masato Mimura
We prove that for any euclidean ring R and n at least 6, Gamma=SL_n(R) has no unbounded quasi-homomorphisms. From Bavard's duality theorem, this means that the stable commutator le…

Fixed point properties and second bounded cohomology of universal lattices on Banach space
Masato Mimura
Let B be any Lp space for p in (1,infty) or any Banach space isomorphic to a Hilbert space, and k be a nonnegative integer. We show that if n is at least 4, then the universal latt…
