U - branes and T 3 fibrations

چکیده
We describe eight-dimensional vacuum configurations with varying moduli consistent with the U -duality group SL(2,ZZ) × SL(3,ZZ). Focusing on the latter less-well understood SL(3,ZZ) properties, we construct a class of fivebrane solutions living on lines on a three-dimensional base space. The resulting U -manifolds, with five scalars transforming under SL(3), admit a Ricci-flat Kähler metric. Based on the connection with special lagrangian T 3 fibered Calabi-Yau 3-folds, this construction provides a simple framework for the investigation of Calabi-Yau mirrors.

Conifold Type Singularities,
In this paper we discuss various aspects of non-compact models of CFT of the type: ∏NL j=1{N = 2 Liouville theory}j ⊗ ∏NM i=1{N = 2 minimal model}i and ∏NL j=1{SL(2;R)/U(1) supercoset}j⊗ ∏NM i=1 {N = 2 minimal model}i. These models are related to each other by T-duality. Such string vacua are expected to describe non-compact Calabi-Yau compactifications, typically ALE fibrations over (weighted)...
متن کاملD-Branes in Nongeometric Backgrounds
“T-fold” backgrounds are generically-nongeometric compactifications of string theory, described by T fibrations over a base N with transition functions in the perturbative T-duality group. We review Hull’s doubled torus formalism, which geometrizes these backgrounds, and use the formalism to constrain the D-brane spectrum (to leading order in gs and α ) on T fibrations over S with O(n, n;Z) mon...

متن کاملT-duality with H-flux: non-commutativity, T-folds and G × G structure
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-dual of a three-torus with uniform flux is embedded into a generalized complex six-torus, and the non-geometry is probed by D0-branes regarded as generalized complex submanifolds. The noncommutativity scale, which is p...
