Workshop on Quantum Symmetries

October 16-18, 2019

ICTP-SAIFR, São Paulo, Brazil

Auditorium of IFT-UNESP


Symmetry in nature and in mathematics may be encoded by groups of symmetry operations, or more generally by the action of Hopf algebras (quantum symmetry). Several powerful tools are used for understanding these actions, such as Lie theory, group theory, tensor categories, fusion categories, and cohomology. The areas to which these ideas apply range from such classical subjects as geometry, combinatorics and algebra to quantum computations, vertex algebras and conformal field theories.

Despite the growing number of people working on quantum symmetries in these different areas and a reasonable number of conferences in the respective areas, the cross-pollination of these different subjects at a single conference is rare and the communities interested in quantum symmetries for different reasons do not have substantial overlap.

The goal of this workshop is to bring together specialists and young mathematicians specializing in these areas to develop newly emerging connections and foster communication and sharing of ideas. This event will consist of research and panoramic talks related to several subject areas united by their applications to quantum symmetries.

There is no registration fee.
