Sublinear rigidity of lattices in semisimple Lie groups
Abstract
I will talk about the coarse geometry of lattices in real semisimple Lie groups. One great result from the 1990s is the quasi-isometric rigidity of these lattices: any group that is quasi-isometric to such a lattice must be, up to some minor adjustments, isomorphic to lattice in the same Lie group. I present a partial generalization of this result to the setting of Sublinear Bilipschitz Equivalences (SBE): these are maps that generalize quasi-isometries in some 'sublinear' fashion.

Patterns in Science and Art - Liliane Lijn, Marcus du Sautoy and Fatos Ustek with Conrad Shawcross
The search for and creation of patterns is intrinsic to both science and art. But so is the desire to understand how and why those patterns break down and to uncover the implications for the scientist and the artist.
Artist Liliane Lijn, curator Fatos Ustek and mathematician Marcus du Sautoy will share their experience and understanding of pattern and where it has taken them in their scientific and artistic careers. Conrad Shawcross will chair the discussion and provide his own unique perspective as represented by his 'Cascading Principles' Exhibition.
Liliane Lijn is an American-born artist who has exhibited at the Venice Biennale, and was recently short listed for her design for the Fourth Plinth in Trafalgar Square. Marcus Sautoy is a mathematician and Professor for the Public Understanding of Science in Oxford. Fatos Ustek is curator of the 'Cascading Principles' exhibition and curator of the sculpture park at Frieze London. Conrad Shawcross is an artist specialising in mechanical sculptures based on philosophical and scientific ideas.
