Abstract: (arXiv)
We study the dimensional reduction of the , ten-dimensional Heterotic Supergravity to four dimensions, at leading order in , when the internal space is a coset manifold. Then we apply the formalism using as internal manifolds all possible six-dimensional non-symmetric coset spaces, namely and , which moreover are nearly-K\'{a}hler manifolds and preserve the supersymmetric spectrum. In these cases we determine the effective actions which turn out to describe four-dimensional supergravities of the no-scale type.- supergravity: heterotic
