algebras and Tensor Hierarchies in Exceptional Field Theory and Gauged Supergravity
Yago Cagnacci, Tomas Codina, Diego Marques
We show how the gauge and field structure of the tensor hierarchies in Double and Exceptional Field Theory fits into algebras. Special attention is paid to re…

The bosonic string on string-size tori from double field theory
Yago Cagnacci, Mariana Graña, Sergio Iguri +1
We construct the effective action for toroidal compactifications of bosonic string theory from generalized Scherk-Schwarz reductions of double field theory. The enhanced gauge symm…

Spectral flow and conformal blocks in
Yago Cagnacci, Sergio M. Iguri
In this article we investigate the structure of the four-point functions of the -WZNW model. We consider the integral expression for the unflowed four-point correlator invol…
