Non-geometric strings, symplectic gravity and differential geometry of Lie algebroids
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1
Based on the structure of a Lie algebroid for non-geometric fluxes in string theory, a differential-geometry calculus is developed which combines usual diffeomorphisms with so-call…
A bi-invariant Einstein-Hilbert action for the non-geometric string
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1
Inspired by recent studies on string theory with non-geometric fluxes, we develop a differential geometry calculus combining usual diffeomorphisms with what we call beta-diffeomorp…
Moduli Stabilization and Inflationary Cosmology with Poly-Instantons in Type IIB Orientifolds
Ralph Blumenhagen, Xin Gao, Thorsten Rahn +1
Equipped with concrete examples of Type IIB orientifolds featuring poly-instanton corrections to the superpotential, the effects on moduli stabilization and inflationary cosmology…
Bianchi Identities for Non-Geometric Fluxes - From Quasi-Poisson Structures to Courant Algebroids
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1
Starting from a (non-associative) quasi-Poisson structure, the derivation of a Roytenberg-type algebra is presented. From the Jacobi identities of the latter, the most general form…
A Note on Poly-Instanton Effects in Type IIB Orientifolds on Calabi-Yau Threefolds
Ralph Blumenhagen, Xin Gao, Thorsten Rahn +1
The zero mode structure for the generation of poly-instanton corrections for Euclidian D3-branes wrapping complex surfaces in Type IIB orientifolds with O7- and O3-planes is analyz…
Palatini-Lovelock-Cartan Gravity - Bianchi Identities for Stringy Fluxes
Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1
A Palatini-type action for Einstein and Gauss-Bonnet gravity with non-trivial torsion is proposed. Three-form flux is incorporated via a deformation of the Riemann tensor, and cons…
