Description
I will describe a number of non-trivial constraints that arise in smooth heterotic compactifications and can lead to the resulting 4-dimensional, N=1 effective theories being highly restricted in form. These include topological vanishings of heterotic tri-linear couplings, as well other aspects of the potential and constraints on how gauge symmetry is broken and what discrete symmetries can appear.
