SUMMARY:Quantum symmetries of graphs and their generalizations - Moritz We
 ber (Universität des Saarlandes)

DESCRIPTION:Quantum symmetries play an important role in quantum mathemati
 cs. After Woronowicz defined compact quantum groups in the 1980s and Sh. W
 ang defined the quantum permutation group (as the quantum symmetries of n 
 discrete points) in the 1990s\, Banica and Bichon gave definitions of quan
 tum automorphism groups of finite graphs in the 2000s. Building on this\, 
 many more combinatorial structures can be studied with respect to their qu
 antum symmetries. In my talk\, I will briefly survey latest results of my 
 group and myself on quantum symmetries of graphs\, hypergraphs\, matroids 
 and further related quantum group constructions. I might also mention nonl
 ocal games\, who knows.
