Abstract:
Representation theory is about the study of symmetry. In general, construction and classification of representations are the main problems in this field. On the other hand, categorification is the process of finding hidden higher level structure. In this talk, we will give an introduction to the combination of the two notions, which is called the categorical action. Usually the categories comes from geometric spaces that naturally arise in representation theory. Finally, if time permits we will discuss our current work where the motivation comes from the categorification of quantum groups and their actions.
