Query: Lecture Notes on Quiver Representations and Moduli Problems in Algebraic
  Geometry   These lecture notes consist of an introduction to moduli spaces in algebraic
geometry, with a strong emphasis placed on examples related to the theory of
quiver representations. The goal is to provide the background necessary to
understand the construction of the moduli spaces of stable and semistable
quiver representations due to King, Nakajima's quiver varieties, as well as
some 'quiver versions' of existing moduli spaces of algebra-geometric objects.
