N2 - Classical heterotic string solutions with spontaneously broken d = 4, N = 1, 2 or 4 supersymmetry have been recently formulated via coordinate-dependent compactifications. We construct the corresponding low-energy effective lagrangians by means of generalized dimensional reductions à la Scherk-Schwarz. We show that these dimensional reductions of d = 10, N = 1 supergravity + Yang-Mills can be interpreted as special "gaugings" of the resulting d = 4, N = 4 theory, characterized by a positive semidefinite potential. We also describe in detail the properties of the d = 4, N = 1 models obtained from the N = 4 ones by a consistent Z2 × Z2′ truncation.
