A principal torus bundle over a complex manifold with even dimensional fiber
and characteristic class of type (1,1) admits a family of generalized complex
structures. We show that such a generalized complex structure is equivalent to
the product of the complex structure on the base and the symplectic structure
on the fiber in a tubular neighborhood of the fiber. This has consequences for
the generalized Dolbeault cohomology of the bundle.Comment: 19 page
