Abstract: Abstract We compute the monodromy matrices on the special geometry of 4d $$ \mathcal{N} $$ N = 2 Heterotic-IIA dual vacua in some simple cases by numerical evaluation of the period integrals, without assuming a… read more here.

Abstract: Abstract Vacuum compactifications may suffer from instabilities under small perturbations or tunnel effects; both are difficult to analyze. In this paper we consider the issue from a higher-dimensional perspective. We first look at how stability… read more here.

DOI: 10.1007/jhep08(2019)014
Abstract: Abstract We describe a new procedure to obtain consistent backgrounds that uplift vacua and deformations of various maximal gauged supergravities by taking a known solution and performing singular limits along the moduli space of the… read more here.
