Description

I will show how to quickly check stability under many non-perturbative decay channels for several old and new non-supersymmetric AdS vacua in type II string theory, on coset spaces, sphere fibrations, and Kähler–Einstein manifolds. I will do so using calibrations, which are more commonly used for supersymmetric vacua. I will also mention how some of the same spaces can be used to produce new AdS solutions for the heterotic SO(16)xSO(16) theory
