Exploring Double Field Theory

Understand

We present a flux formulation of Double Field Theory, in which geometric and non-geometric fluxes are dynamical and field-dependent.

• Gauge consistency imposes a set of quadratic constraints on the dynamical fluxes, which can be solved by truly double configurations.
• The constraints are related to generalized Bianchi Identities for (non-)geometric fluxes in the double space, sourced by (exotic) branes.
• Following previous constructions, we then obtain generalized connections, torsion and curvatures compatible with the consistency conditions.
