# Born sigma-models for para-Hermitian manifolds and generalized T-duality

@article{Marotta2021BornSF, title={Born sigma-models for para-Hermitian manifolds and generalized T-duality}, author={Vince Marotta and Richard J Szabo}, journal={Reviews in Mathematical Physics}, year={2021} }

We give a covariant realization of the doubled sigma-model formulation of duality-symmetric string theory within the general framework of para-Hermitian geometry. We define a notion of generalized metric on a para-Hermitian manifold and discuss its relation to Born geometry. We show that a Born geometry uniquely defines a worldsheet sigma-model with a para-Hermitian target space, and we describe its Lie algebroid gauging as a means of recovering the conventional sigma-model description of a…
