of bundles over rational surfaces and elliptic curves Abstract: It is known from the work of
Friedman-Morgan-Witten and Donagi that del Pezzo surfaces of degree 9? n one-to-one correspond to flat
En bundles over an elliptic curve. In this talk I will explain my joint work
with Jiajin Zhang, in which we construct G-bundles over a broader class of
rational surfaces for any simple, compact and simply-connected Lie group,
simply laced or not. Then we extend the above correspondence to all flat G bundles over an elliptic curve. |
