Quantum graphs and quantum Cuntz-Krieger algebra

Geometría Noconmutativa del Atlántico Sur (GeNoCAS)

Titulo: Quantum graphs and quantum Cuntz-Krieger algebra
En esta oportunidad va a hablar Christian Voigt (Glasgow)

Resumen:

In this talk I will give an introduction to quantum graphs, a relatively recent concept with connections to graph theory, quantum groups, and quantum information. I will discuss some examples, and then explain how one can associate an operator algebra to a quantum graph, in analogy to the construction of Cuntz-Krieger algebras. For certain examples this leads to a rather unexpected new description of the Cuntz algebras O_n.
