$\mathcal{N}=1$ Geometric Supergravity and chiral triples on Riemann surfaces

Vicente Cortés, C. I. Lazaroiu, C. S. Shahbazi

We construct a global geometric model for the bosonic sector and Killing spinor equations of four-dimensional $\mathcal{N}=1$ supergravity coupled to a chiral non-linear sigma mode…
