Abstract:Let $ Q = (Q_0,Q_1) $ be a quiver with vertices $ Q_0 $ and arrows $ Q_1 $. A representation of $Q$ is a family of vector spaces $ (V_i)_{i \in Q_0} $ and linear maps $ (f_{ij}) _{i\rightarrow j \in Q_1} $ between the vector spaces. In this talk, we will consider the category of representations of the quiver, or, equivalently, the module category of its path algebra. Then, we will illustrate the links between quiver representations and two other mathematical concepts; quantum groups and cluster algebras.
