A Kirwan Blowup and Trees of Vector Bundles
- 568 Downloads
In the paper (Markushevich et al., Cent Eur J Math 10:1331–1355, 2012) a conceptual description of compactifications of moduli spaces of stable vector bundles on surfaces has been given, whose boundaries consist of vector bundles on trees of surfaces. In this article a typical basic case for the projective plane is described explicitly including the construction of a relevant Kirwan blowup.
