Title: Coalgebras, comodules and coends

Abstract: In this talk we will consider coalgebras, comodules, and group like elements, that is the dual notions to algebras, modules and the group of units respective to an algebra over a vector space. We will then see how this allows us to study $\mathbb{k}$-linear categories via the Coend construction as well as being the groundwork required for Deligne's tensor product of finite Abelian categories.
