Lecture
Group Actions on Sets
Description
This lecture covers the concept of group actions on sets, defined as a group homomorphism from a group G to the group of bijections of a set X. It explores the equivalent definition of a group action as a function from the Cartesian product of G and X to X, illustrating the properties of such actions. The lecture also discusses the adjunction of examples to provide a deeper understanding of group actions.
