要旨:
A number of issues in heterotic double field theory are studied. This
includes the analysis of the T-dual configurations of a flat constant gauge
flux background, which turn out to be non-geometric. Performing a field
redefinition to a non-geometric frame, these T-duals take a very simple form
reminiscent of the constant Q- and R-flux backgrounds. In addition, it is shown
how the analysis of arXiv:1304.2784 generalizes to heterotic generalized
geometry. For every field redefinition specified by an O(D,D+n) transformation,
the structure of the resulting supergravity action is governed by the
differential geometry of a corresponding Lie algebroid.
