Explore the mathematical journey from group actions to actegories in this 55-minute conference talk delivered by Kathryn Hess from École Polytechnique Fédérale de Lausanne at the Fields Institute. Delve into advanced algebraic topology concepts as the speaker bridges fundamental group theory with the more sophisticated framework of actegories, examining how group actions can be generalized and extended into this categorical setting. Gain insights into the theoretical foundations and applications of these mathematical structures, understanding their role in modern algebraic topology and category theory. Learn about the connections between classical group actions and their categorical generalizations, exploring how this progression opens new avenues for mathematical research and applications in topology.
