[hep-th] Seminar grupe za gravitaciju, cestice i polja, 18. februar 2022

[Marija Dimitrijevic Ciric]

Zdravo svima,

evo najave seminara, koji ce u petak 18. februara 2022. drzati Ilija 
Ivanisevic (Institut za fiziku, Beogradu)

Naslov: Courant algebroids in bosonic string theory

Asptrakt: 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.
