On framed quiver moduli
Framed quiver moduli, introduced by Nakajima in [2],
parametrize certain ßtable" pairs consisting of a quiver
representation and a map to a fixed graded vector space. They
were used in [2] as a preliminary step towards the
definition of Nakajima's quiver varieties.
In the first part of the talk, some basic geometric properties
of framed quiver moduli for quivers without oriented cycles
will be discussed, with emphasis on their cohomology.
In the second part, the use of framed quiver moduli for quantum
group constructions, in the spirit of the work of Beilinson,
Lusztig and MacPherson [1], will be discussed.
