Title : Approximate lattices and quasi-morphisms 

Abstract: Approximate lattices are approximate groups that are â€largeâ€ and discrete
in some ambient group.  The exact notion of â€largeâ€ is up for debate.  In this talk
I will discuss how to construct exotic examples of approximate lattices from
quasimorphisms, and the dynamics/point processes they give rise to, and how radically
different they are from classical examples.  No prior knowledge of approximate lattices
will be assumed.  Joint work with Tobias Hartnick (Karlsruhe)
