Title: Moduli of tensor stable points and refined representations


Abstract: This is joint work with Daniel Chan (UNSW Sydney). Moduli 
spaces are a fruitful way of studying a given abelian category, take for 
example the moduli of point-like objects in non-commutative projective 
spaces or the moduli of representations of the McKay quiver. These 
examples yield moduli varieties, elliptic curves and minimal resolutions 
of Kleinian singularities respectively. Sometimes, however, the problem 
lends itself better to algebraic stacks as in the case of Ringel's 
canoncial algebras and weighted projective lines. We will start with a 
stack and a direct sum of line bundles that form a tilting bundle and 
recover the stack from the corresponding category of quiver representations.
