Optical geometries
Anna Fino, Thomas Leistner, Arman Taghavi-Chabert
We study the notion of optical geometry, defined to be a Lorentzian manifold equipped with a null line distribution, from the perspective of intrinsic torsion. This is an instance…
Special Hermitian structures on suspensions
Anna Fino, Gueo Grantcharov, Misha Verbitsky
Motivated by the construction based on topological suspension of a family of compact non-Kähler complex manifolds with trivial canonical bundle given by L. Qin and B. Wang in [QW]…
Generalized Kähler manifolds via mapping tori
Beatrice Brienza, Anna Fino
Starting from the product of a -torus and a compact Kähler (respectively, hyperKähler) manifold we construct via mapping tori generalized Kähler manifolds of split (respectiv…
The twisted G equation for strong G-structures with torsion
Anna Fino, LucÃa MartÃn-Merchán, Alberto Raffero
We discuss general properties of strong G-structures with torsion and we investigate the twisted G equation, which represents the G-analogue of the twisted Calabi-Yau e…
