[phys4phys] Group for Gravitation, Particle and Fields on-line seminar, Friday 18 February 2022

[Marija Dimitrijevic Ciric]

Dear colleagues,

You are cordially invited to the online seminar of the Group for 
Gravitation, Particles and Fields, which will be held on Friday, 18 
February 2022 at 11:00 via the BigBlueButton platform (link is given 
below).


The talk entitled

Courant algebroids in bosonic string theory

will be given by Ilija Ivanisevic (Institute of Physics, Belgrade).

Abstract: We analyze bosonic string symmetry transformations and their 
relations with  T-duality in the framework of generalized geometry. The 
generator governing symmetry transformations can be described simply as 
the inner product of generalized vectors and its algebra produces the 
Courant bracket as the T-dual invariant extension of the Lie bracket, 
while T-duality can be interpreted as an isomorphism between Courant 
algebroids. We show how different O(D, D) transformations give rise to 
different twists of the Courant bracket that feature string theory 
relevant fluxes.
