چکیده
|
We find that (massive) iia backgrounds that admit a $$ {g}_2ltimes {mathbb{r}}^8 $$ invariant killing spinor must exhibit a null killing vector field which leaves the killing spinor invariant and that the rotation of the killing vector field satisfies a certain g2 instanton condition. this result together with those in [4] and [5] complete the classification of geometries of all (massive) iia backgrounds that preserve one supersymmetry. we also explore the geometry of a class of backgrounds which admit a $$ {g}_2ltimes {mathbb{r}}^8 $$ invariant killing spinor and where in addition an appropriate 1-form bilinear vanishes. in all cases, we express the fluxes of the theory in terms of the geometry.
