Moduli of sheaves from moduli of Kronecker modules
I will explain how to view the construction of moduli spaces of semistable sheaves on a projective variety as a functorial embedding into more basic projective varieties, namely moduli spaces of semistable Kronecker modules. This sheds new light on how to construct `theta functions', i.e. natural projective coordinates on these moduli spaces. This is joint work with Alastair King. Preprint math.AG/0602032.
