Instanton decay and holomorphic surgery for vector bundles Elizabeth Gasparim
Аннотация: I will define holomorphic surgery and give applications to decay of instantons. Let $S$ be a sphere embedded in a 4-dimensional manifold, with negative self-intersection $SS=–k$. I will show that the behavior of instanton decay and instanton moduli depends on $k$. In particular, if $k\ge 2$ decay is obstructed.
