奇怪的二元性和希钦/WZW连接

Strange duality and the Hitchin/WZW connection

Prakash Belkale

摘要:

对于正亏格的紧致黎曼曲面X,在秩为r和水平为k的丛的模上的某个θ丛的截面空间允许一个自然映射到秩为k和水平为r的相似截面空间(的对偶)(奇怪的对偶同构)。当X在一个族中变化时,同构的两边都带有射影联络。我们证明了这个映射是(射影)平坦的。

英文摘要:

For a compact Riemann surface X of positive genus, the space of sections of certain theta bundle on moduli of bundles of rank r and level k admits a natural map to (the dual of) a similar space of sections of rank k and level r (the strange duality isomorphism). Both sides of the isomorphism carry projective connections as X varies in a family. We prove that this map is (projectively) flat.
