DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QGS/9/">Quan
 tum Cuntz-Krieger algebras</a>\nby Christian Voigt (University of Glasgow\
 , UK) as part of Quantum Groups Seminar [QGS]\n\n\nAbstract\nThe notion of
  a quantum graph\, a concept going back to work of Erdos-Katavolos-Shulman
  and Weaver\, provides a noncommutative generalisation of finite graphs. Q
 uantum graphs play an intriguing role in the analysis of quantum symmetrie
 s of graphs via monoidal equivalences\, and\nnaturally appear also in quan
 tum information theory.\n\nIn this talk\, I will discuss the construction 
 of certain C*-algebras associated with directed quantum graphs\, in analog
 y to the definition of Cuntz-Krieger algebras\, and illustrate this with s
 ome examples. (Joint work with M. Brannan\, K. Eifler\, M. Weber.)\n
