Type-II Calabi-Yau compactifications, T-duality and special geometry in general spacetime signature

M. Medevielle, T. Mohaupt, G. Pope

We obtain the bosonic Lagrangians of vector and hypermultiplets coupled to four-dimensional $\mathcal{N}=2$ supergravity in signatures $(0,4)$, $(1,3)$ and (2,2) by compactificatio…
