Abstrakt:
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, published in 2007 and 2009.
