Moduli of algebraic curves - Wikipedia

The moduli stack classifies families of smooth projective curves of genus g, together with their isomorphisms. When g > 1, this stack may be compactified by adding new "boundary" points which correspond to stable nodal curves (together with their isomorphisms). A curve is stable if it has only a finite group of automorphisms. The resulting stack is denoted . Both moduli stacks carry universal families of curves. One can also define coarse moduli spaces representing isomorphis… Webgroup is an open and smooth subvariety, and is the fine moduli space of the functor M0 g,n of stable curves with trivial automorphism group. Thus, there is a universal family C0 g,n −→π M0 g,n. The spaces M g,ncan be decomposed in terms of the stable graphs: Proposition ([Sch, Prop 4.14]). Let g,n≥0 with 2g−2 + n>0.

WebThis makes the space of holomorphic structures (i.e. the space of bundles with a fixed topological type) into an affine space. The group of complex automorphisms of the bundle acts on this space, and the quotient is the moduli space of holomorphic bundles. If you don't restrict to stable bundles, this quotient space fails to be Hausdorff.
