introduction
- replace cluster variables by modules
notions
- quiver : oriented graph
- represetation of a quiver : collection of vector space and linear maps between them
- homomorphism of 2 quiver representations
- path algebra of a quiver
- given a quiver Q, a path p is a sequence of arrows with some conditions
- path algebra : set of all k-linear combinations of all paths (including e_i's)
- p_1p_2 will correspond to a composition \(p_2\circ p_1\) of two maps (U\overset{P_2}{\rightarrow }V\overset{P_1}{\rightarrow }W)
- quiver representation is in fact, a representaion of path algebra of a quiver
- quiver has finite type of there are finitely many indecomposables
\thm (Gabriel)
A connected quiver Q has finite type iff corresponding graph is Dynking diagram (A,D,E)
outline of a proof of the periodicity conjecture for pairs of Dynkin diagrams
