Brackets, Sigma Models and Integrability of Generalized Complex Structures
It is shown how derived brackets naturally arise in sigma-models via Poisson-
or antibracket, generalizing a recent observation by Alekseev and Strobl. On
the way to a precise formulation of this relation, an explicit coordinate
expression for the derived bracket is obtained. The generalized Nijenhuis
tensor of generalized complex geometry is shown to coincide up to a de-Rham
closed term with the derived bracket of the structure with itself, and a new
coordinate expression for this tensor is presented. The insight is applied to
two known two-dimensional sigma models in a background with generalized complex
structure. Introductions to geometric brackets on the one hand and to
generalized complex geometry on the other hand are given in the appendix.Comment: 48 pages (27 without appendix), created with LyX, based on LaTeX,
