Monoidal categorifications of cluster algebras

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

 

 

finite type quiver classfication

• 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)

 

 

Caldero-Chapoton formula

CC(V) =\chi_{V}
