Título: String structures and Courant algebroids 

Resumo: A string structure is a higher analogue of a spin structure on manifolds. Its existence is obstructed by the first Pontryagin class, which itself is tied to a certain class of transitive Courant algebroids. In this talk, I will review these two notions and explain how they are linked by a reduction procedure introduced by Bursztyn-Cavalcanti-Gualtieri. Time permitting, I will explain how to do geometry and implement T-duality on these transitive Courant algebroids.
