Let M be a smooth compact connected oriented manifold of dimension at least two endowed with a volume form μ. We show that every homogeneous quasi-morphism on the identity component Diff0(M, μ) of the group of volume-preserving diffeomorphisms of M, which is induced by a quasi-morphism ...
Any compact Lie group carries a bi-invariant metric such that there are no small subgroups. From now on, let G be equipped with a bi-invariant metric d. We con- struct quasi-morphisms F → G, where F = F (S) as in Section 2. Let σ∈ ℓ∞(G). We define gσ : F → G...
Cup products provide a natural approach to access higher bounded cohomology groups. We extend vanishing results on cup products of Brooks quasimorphisms of
We show for very general classes of measures on locally compact second countable groups that every Borel measurable quasimorphism is at bounded distance from a quasi-biharmonic one. This allows us to deduce non-degenerate central limit theorems and laws of the iterated logarithm for such quasi...

Quasi-compact Quasi-separated Tensor functor Tannaka reconstruction 1. Introduction For every morphism of schemes f:Y→X we have a pullback functor ⁎f⁎:Qcoh(X)→Qcoh(Y) between categories of quasi-coherent sheaves. It preserves direct sums, cokernels and tensor products, i.e. it is ...
