Disputation: Lucas Yudi Hataishi

The PhD defence will be partially digital, in room 1259, Abels Utsikt - Niels Henrik Abels hus and streamed directly using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the disputation.

Ex auditorio questions: the chair of the defence will invite the audience to ask questions ex auditorio at the end of the defence. If you would like to ask a question, click 'Raise hand' and wait to be unmuted.

Operator algebras were born out of the attempt to give mathematically rigorous foundations to quantum mechanics, and its development has been higly influenced by the mathematical approaches to understanding quantum field theories. Symmetries, central characters in physics, are understood in these approaches as symmetries of operator algebras. With the changes of paradigms concerning symmetries in physics, there came changes of paradigms regarding the concept of symmetries of operator algebras.

This thesis elaborates on two main ideas: actions of quantum groups and C*-tensor categories. One can think of those as extensions to the category of noncommutative topological spaces of group theory and representation theory, respectively.

The topics we cover are: boundary actions, equivariant injectivity, Yetter-Drinfeld C*-algebras and factorization homology.
