DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/137/">G
 eometry of approximate subgroups</a>\nby Tobias Hartnick (Karlsruher Insti
 tut für Technologie) as part of Geometry and topology online\n\nLecture h
 eld in Room B3.02 in the Zeeman Building\, University of Warwick.\n\nAbstr
 act\nIn this lecture\, which is independent of the first two ones\, we wil
 l explain some of the more geometric aspects of approximate subgroups rela
 ted to geometric group theory\, measure equivalence and bounded cohomology
 . A key player in this game is a certain ample groupoid constructed from t
 he local patterns of the underlying point set. \n\nThis is based on joint 
 works with Björklund\, Cordes\, Sarti and Tonić.\n
