Heterotic compactifications with fluxes
I will describe the complex geometry underlying a
compactification of both weakly and strongly coupled Heterotic theory
in the presence of a background flux. I will discuss the
classification of such geometries with an emphasis on the gauge fields
and anomaly cancellation. I will describe explicit constructions of
heterotic compactifications in the presence of fluxes as well as a
no-go theorem establishing the sharpness of the existence results.
