T-duality, Non-geometry and Lie Algebroids in Heterotic Double Field Theory
نویسندگان
چکیده
A number of issues in heterotic double field theory are studied. This includes the analysis of the T-dual configurations of a flat constant gauge flux background, which turn out to be non-geometric. Performing a field redefinition to a nongeometric frame, these T-duals take a very simple form reminiscent of the constant Qand R-flux backgrounds. In addition, it is shown how the analysis of arXiv:1304.2784 generalizes to heterotic generalized geometry. For every field redefinition specified by an O(D,D+n) transformation, the structure of the resulting supergravity action is governed by the differential geometry of a corresponding Lie algebroid. 1 ar X iv :1 41 1. 31 67 v2 [ he pth ] 2 8 N ov 2 01 4

Heterotic effective action and duality symmetries revisited
The dimensional reduction of heterotic supergravity with gauge fields truncated to the Cartan subalgebra exhibits a continuous O(d, d+ 16;R) global symmetry, related to the O(d, d+16;Z) T-duality of heterotic strings on a d-torus. The O(d, d+16;R) symmetry is not present, however, if the supergravity reduction is done including the full set of E8×E8 or SO(32) gauge fields. We analyze which dual...
متن کاملSe p 20 05 DUALITY AND EQUIVALENCE OF MODULE CATEGORIES IN NONCOMMUTATIVE GEOMETRY
This is the first in a series of papers that deals with duality statements such as Mukai-duality (T-duality, from algebraic geometry) and the Baum-Connes conjecture (from operator K-theory). These dualities are expressed in terms of categories of modules. In this paper, we develop a general framework needed to describe these dualities. In various geometric contexts, e.g. complex geometry, gener...

We complete the construction of the double Lie algebroid of a double Lie groupoid begun in the first paper of this title. We extend the construction of the tangent pro-longation of an abstract Lie algebroid to show that the Lie algebroid structure of any LA-groupoid may be prolonged to the Lie algebroid of its groupoid structure. In the case of a double groupoid, this prolonged structure for ei...
متن کاملString Dualities from Matrix Theory
We suggest that the (2,0) six dimensional field theory compactified on S × K3 is the Matrix model description of both M-theory on K3 and the Heterotic string on T . This proposal is different from existing proposals for the Heterotic theory. Different limits of the base space geometry give the different space-time interpretations, making Mtheory/Heterotic duality manifest. We also present parti...
متن کاملHeterotic-Type II String Duality and the H-Monopole Problem
Since T-duality has been proved only perturbatively and most of the heterotic states map into solitonic, non-perturbative, type II states, the 6-dimensional string-string duality between the heterotic string and the type II string is not sufficient to prove the S-duality of the former, in terms of the known T-duality of the latter. We nevertheless show in detail that the perturbative T-duality,...
