O(d,d)-Duality in String Theory
Felix Rennecke
A new method for obtaining dual string theory backgrounds is presented. Preservation of the Hamiltonian density and the energy momentum tensor induced by O(d,d)-transformations lea…
A Note on the CFT Origin of the Strong Constraint of DFT
Andre Betz, Ralph Blumenhagen, Dieter Lust +1
In double field theory, motivated by its field theoretic consistency, the level matching condition is generalized to the so-called strong constraint. In this note, it is investigat…
The Intriguing Structure of Non-geometric Frames in String Theory
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +2
Non-geometric frames in string theory are related to the geometric ones by certain local O(D,D) transformations, the so-called -transforms. For each such transformation, we show…
Non-geometric strings, symplectic gravity and differential geometry of Lie algebroids
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1
Based on the structure of a Lie algebroid for non-geometric fluxes in string theory, a differential-geometry calculus is developed which combines usual diffeomorphisms with so-call…
A bi-invariant Einstein-Hilbert action for the non-geometric string
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1
Inspired by recent studies on string theory with non-geometric fluxes, we develop a differential geometry calculus combining usual diffeomorphisms with what we call beta-diffeomorp…
Bianchi Identities for Non-Geometric Fluxes - From Quasi-Poisson Structures to Courant Algebroids
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1
Starting from a (non-associative) quasi-Poisson structure, the derivation of a Roytenberg-type algebra is presented. From the Jacobi identities of the latter, the most general form…
