Query: Orientability for gauge theories on Calabi-Yau manifolds   We study orientability issues of moduli spaces from gauge theories on
Calabi-Yau manifolds. Our results generalize and strengthen those for
Donaldson-Thomas theory on Calabi-Yau manifolds of dimensions 3 and 4. We also
prove a corresponding result in the relative situation which is relevant to the
gluing problem in DT theory.
