Abstract
We investigate quantum corrections to the classical four-dimensional lowenergy
effective action of type II string theory compactified on SU(3) structure geometries.
Various methods previously developed for Calabi-Yau compactifications are adopted to
constrain – under some simple assumptions about the low-energy degrees of freedom – the
leading perturbative corrections to the moduli space metrics in both α
0 and the string
coupling constant. We find that they can be parametrized by a moduli dependent function
in the hypermultiplet sector and a constant in the vector multiplet sector. We argue that
under specific additional assumption they take – in complete analogy to the Calabi-Yau
case – a universal form which depends only on the Euler characteristic of the six-dimensional
compact space.
