要旨:
Assuming that the duality symmetry present for heterotic orbifold compactifications extends to the blow-up orbifold, we derive conditions for the Kähler potential for the moduli and for the cubic Yukawa couplings among the matter fields. This is done, perturbatively in the blowing up procedure, on the level of the low energy effective action. The analysis is based on constraints from N = 2 space-time supersymmetry which are due to the relation between heterotic and type II theories compactified on the same internal space.
