The moduli space of hyper-Kähler four-fold compactifications
نویسنده
چکیده
I discuss some aspects of the moduli space of hyper-Kähler four-fold compactifications of type II and Mtheories. The dimension of the moduli space of these theories is strictly bounded from above. As an example I study Hilb(K3) and the generalized Kummer variety K(T ). In both cases RR-flux (or G-flux in M-theory) must be turned on, and we show that they give rise to vacua with N = 2 supersymmetry upon turning on appropriate fluxes. An interesting subtlety involving the symmetric product limit S(K3) is pointed out.

Hyper-Kähler Hierarchies and their twistor theory
A twistor construction of the hierarchy associated with the hyper-Kähler equations on a metric (the anti-self-dual Einstein vacuum equations, ASDVE, in four dimensions) is given. The recursion operator R is constructed and used to build an infinite-dimensional symmetry algebra and in particular higher flows for the hyper-Kähler equations. It is shown that R acts on the twistor data by multiplic...
متن کاملOn the Hypermultiplet Moduli Space of Heterotic Compactifications with Small Instantons
We propose a method of computing the α corrections to the moduli space of hypermultiplets of N = 2 four-dimensional vacua resulting from compactifications of heterotic strings on K3 × T . The method is based on relating the hypermultiplet moduli space of the original model to the vector multiplet moduli space of the ”mirror” one which can be computed exactly due to Heterotic/Type II duality. We...
متن کاملString Loop Corrections to Kähler Potentials in Orientifolds
We determine one-loop string corrections to Kähler potentials in type IIB orientifold compactifications with either N = 1 or N = 2 supersymmetry, including D-brane moduli, by evaluating string scattering amplitudes.
متن کاملKähler Potentials of Chiral Matter Fields for Calabi-Yau String Compactifications
The Kähler potential is the least understood part of effective N = 1 supersymmetric theories derived from string compactifications. Even at tree-level, the Kähler potential for the physical matter fields, as a function of the moduli fields, is unknown for generic Calabi-Yau compactifications and has only been computed for simple toroidal orientifolds. In this paper we describe how the modular d...
متن کاملKähler versus Non-Kähler Compactifications
We review our present understanding of heterotic compactifications on non-Kähler complex manifolds with torsion. Most of these manifolds can be obtained by duality chasing a consistent F-theory compactification in the presence of fluxes. We show that the duality map generically leads to non-Kähler spaces on the heterotic side, although under some special conditions we recover Kähler compactific...
