Speaker: Christian Voigt Title: Quantum Symmetry Abstract: Like virtually any other
mathematical structure, the notion of a graph comes with a natural concept of symmetry,
specifying what it means for two graphs to be isomorphic.  In recent years, the idea of
quantum symmetry as emerged, leading to an intriguing new way of comparing graphs which
is more flexible than “classical” isomorphism.  In this talk I will explain what
quantum symmetry is and discuss some basic examples, indicating connections with the
theory of operator algebras and beyond.
