#### High Energy Theory Seminar - Barton Zwiebach, MIT - Double Field Theory: Geometry and Applications

Abstract:

Double field theory is an approach to make T-duality

manifest in low energy Lagrangians by doubling the

number of spacetime dimensions. It features an

intriguing generalization of Riemannian

geometry and may help understand some aspects

of string theory effective actions and compactification.
