Title: Everything you wanted to know about gerbes but were afraid to ask
Speaker: Gil Cavalcanti
First, I will cover the material alluded to in the title. In the remaining two hours, I will define gerbes, try to give an idea of when they appear, talk about connections, loop spaces, Courant algebroids, vector bundle twists and topological T-duality. I will run out of time at some point in the middle.
