Heterotic horizons and AdS backgrounds that preserve 6 supersymmetries
Georgios Papadopoulos
We prove, under suitable global assumptions, that the only heterotic horizons with closed 3-form field strength that preserve strictly 6 supersymmetries have spatial horizon sectio…

Derivations, holonomy groups and heterotic geometry
G. Papadopoulos
We investigate the superalgebra of derivations generated by the fundamental forms on manifolds with reduced structure group. In particular, we point out a relation between the alge…
