This is a talk reporting my understanding of local space introduced by Ivan Mirkovic.
For a reductive group G, we have the remarkable object loop Grassmannian. One would like to generalize this notion to an arbitary group associated to a quiver. To do this, one needs to look at the global Grassmannian which could be viewed as union of Zastava space which is a local space (has locality property) which is a refined version of factorizable space of Beilinson and Drinfeld. I will explain where I get trouble understanding Ivan if people are interested.
