Moment map flows and the Hecke correspondence for quivers |

| 초록본문(Abstract) | Narasimhan and Ramanan's Hecke correspondence for bundles over curves relates bundles of different degree via a Hecke modification over a point on the curve. In the 1990s, Nakajima used an analogous correspondence for quiver varieties (Hecke modifications of bundles over an ALE 4-manifold) to give a geometric construction of representations of affine Kac-Moody algebras and quantum affine algebras. In this talk I will give an analytic interpretation of Nakajima's Hecke correspondence via the gradient flow of the norm-square of a moment map. |
