Basic equivariant gerbes on non-simply connected compact simple Lie groups. (arXiv:1712.08294v1 [math.DG])
来源于:arXiv
This paper computes the obstruction to the existence of equivariant
extensions of basic gerbes over non-simply connected compact simple Lie groups.
By modifying a (finite dimensional) construction of Gaw\c{e}dzki-Reis [J. Geom.
Phys. 50(1):28-55, 2004], we exhibit basic equivariant bundle gerbes over
non-simply connected compact simple Lie groups. 查看全文>>
