Fri, 16 Dec 2016 05:37:30 +0000https://www.gsacademicreflections.com/?p=9099#comment-96[…] Building on my earlier work on T-branes and F-theory, here I will show how De Sitter space emerges from an expansion of the D7-brane action around a T-brane background in the presence of 3-form supersymmetry breaking fluxes: this is crucial since de Sitter space is unstable in quantum gravity, while a D7-brane action resolves the instability. "T-branes are a non-abelian generalization of intersecting branes in which the matrix of normal deformations is nilpotent along some subspace", and it is truly remarkable that "the simplest heterotic string compactifications are dual to T-branes in F-theory." Recalling that the pull-back on the D7-brane worldvolume is given by: […]
