Abstract: T-duality is an ubiquitous duality in theoretical physics, its most well-known incarnation being the duality between type IIA string theory compactified on a circle of radius R and type IIB theory on a circle of radius 1/R. I will give an overview of T-duality, taking the perspective that it can be viewed as a transform of geometric spaces and examining its affect on latent geometric structures. In general, geometric structures will transform under T-duality in highly nontrivial ways: for example complex structures can become symplectic, topological features can become noncommutative deformations, and metrics can become flat gerbes.
