Weakly maximal representations of surface groups
Gabi Ben Simon, Marc Burger, Tobias Hartnick +2
We introduce and study a new class of representations of surface groups into Lie groups of Hermitian type, called weakly maximal representations. They are defined in terms of invar…

Quasi-Total Orders and Translation Numbers
Gabi Ben Simon, Tobias Hartnick
We show that a group admits a non-zero homogeneous quasimorphism if and only if it admits a certain type of action on a poset. Our proof is based on a construction of quasimorphism…

Bounded cohomology, Higgs bundles, and Milnor-Wood inequalities
Tobias Hartnick, Andreas Ott
We explain how the generalized Milnor-Wood inequality for reductive representations of a cocompact complex-hyperbolic lattice into a Hermitian Lie group translates, under the non-a…
