Title: Gerbes on G2-manifolds

Abstract: On a projective complex manifold, the Abelian group of Divisors (Div) maps onto that of holomorphic line bundles (the Picard group). I shall explain a similar construction for G2-manifolds. This uses coassociative submanifolds to define an analogue of Div, and a gauge theoretical equation for a connection on a gerbe to define an analogue of the Picard group.
