Towards mirror symmetry à la SYZ for generalized Calabi-Yau manifolds
Pascal Grange, Sakura Schafer-Nameki
Fibrations of flux backgrounds by supersymmetric cycles are investigated. For an internal six-manifold M with static SU(2) structure and mirror \hat{M}, it is argued that the produ…
T-duality with H-flux: non-commutativity, T-folds and G x G structure
Pascal Grange, Sakura Schafer-Nameki
Various approaches to T-duality with NSNS three-form flux are reconciled. Non-commutative torus fibrations are shown to be the open-string version of T-folds. The non-geometric T-d…
Tachyon condensation and D-branes in generalized geometries
Pascal Grange, Ruben Minasian
In generalized complex geometry, D-branes can be seen as maximally isotropic spaces and are thus in one-to-one correspondence with pure spinors. When considered on the sum of the t…
D-branes, actions effectives et symétrie miroir
Pascal Grange
This thesis is devoted to derivative corrections to the effective action of D-branes, and to mirror symmetry with D-branes. Series of derivative corrections first predicted by non-…
Modified pure spinors and mirror symmetry
Pascal Grange, Ruben Minasian
It has been argued recently that mirror symmetry exchanges two pure spinors characterizing a generic manifold with SU(3)-structure. We show how pure spinors are modified in the pre…
Tachyon Potential in a Magnetic Field with Anomalous Dimensions
Pascal Grange
Products defined in the context of noncommutative gauge theory allow for an interpolation between exact results on tachyon potentials at zero and large background B-fields. Techniq…
