Double sigma models and double field theory

Presented by: 
N Copland Sogang University
Date: 
Wednesday 29th February 2012 - 16:00 to 17:00
Venue: 
INI Seminar Room 1
Abstract: 
I will show how the equations of motion of double field theory can also be derived as the one-loop background field equations of a double sigma model, both being the vanishing of the generalised Ricci tensor. This raises the possibility of deriving higher order corrections to double field theory from a sigma model approach.
