Supersymmetric Nonlinear Sigma Models on Ricci-flat Kähler Manifolds with O(N) Symmetry
We propose a class of N = 2 supersymmetric nonlinear sigma models on the Ricci-flat Kähler manifolds with O(N) symmetry. ∗ E-mail: [email protected] † E-mail: [email protected] ‡ E-mail: [email protected] String theory propagating in a curved spacetime is described by a conformal invariant nonlinear sigma model in two dimensions. Spacetime supersym...
متن کاملMirror Symmetry and Self-dual Manifolds
We introduce self-dual manifolds and show that they can be used to encode mirror symmetry for affine-Kähler manifolds and for elliptic curves. Their geometric properties, especially the link with special lagrangian fibrations and the existence of a transformation similar to the Fourier-Mukai functor, suggest that this approach may be able to explain mirror symmetry also in other situations.
متن کاملToms Symmetry of Compact Self-Dual Manifolds
We classify compact anti-self-dual Hermitian surfaces and compact four-dimensional conformally flat manifolds for which the group of orientation preserving conformal transformations contains a two-dimensional toms. As a corollary, we derive a topological classification of compact self-dual manifolds for which the group of conformal transformations contains a two-dimensional toms. Mathematics Su...
متن کاملSigma-model symmetry in orientifold models
We investigate in the simplest compact D = 4 N = 1 Type IIB orientifold models the sigma-model symmetry suggested by the proposed duality of these models to heterotic orbifold vacua. This symmetry is known to be present at the classical level, and is associated to a composite connection involving untwisted moduli in the low-energy supergravity theory. In order to study possible anomalies arisin...
متن کاملTwistor spaces, mirror symmetry and self-dual Kähler manifolds
We present the evidence for two conjectures related to the twistor string. The first conjecture states that two super-Calabi Yaus – the supertwistor space and the superambitwistor space – form a mirror pair. The second conjecture is that the B-model on the twistor space can be seen as describing a 4-dimensional gravitational theory, whose partition function should involve a sum over “space-time...
