Query: On the sigma-model of deformed special geometry   We discuss the deformed sigma-model that arises when considering
four-dimensional N=2 abelian vector multiplets in the presence of an arbitrary
chiral background field. In addition, we allow for a class of deformations of
special geometry by non-holomorphic terms. We analyze the geometry of the
sigma-model in terms of intrinsic torsion classes. We show that, generically,
the deformed geometry is non-Kahler. We illustrate our findings with an
example. We also express the deformed sigma-model in terms of the Hesse
potential that underlies the real formulation of special geometry.
