introduction
- replace cluster variables by modules
notions
- quiver : oriented graph
- representation 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
Caldero-Chapoton formula
- CC(V) =\chi_{V}
monoidal categorification
M : monoidal categorification
M is a monoidal categorification of A if the Grothendieck ring of M is isomorphic to A and if
(i) cluster monomials' of A are the classes of real simple objects of M
(ii) cluster variables' of a (including coefficients) are classes of real prime simple objects
\prop
Suppose that A has a monoidal categorification M and also that each object B in M has unique finite composition series
(find simple subobject A_1, then simple subobject of A_2 of B/A_1, etc ... composition series if colleciton of all A's)
Then
(i) each cluster variable of a has positivie Laurent expansion with respect to any cluster
(ii) cluster monomials are linearly independent
