A non Ricci-flat Einstein pseudo-Riemannian metric on a 7-dimensional nilmanifold
Marisa Fernández, Marco Freibert, Jonatan Sánchez
We answer in the affirmative the question posed by Conti and Rossi on the existence of nilpotent Lie algebras of dimension 7 with an Einstein pseudo-metric of nonzero scalar curvat…
On -structures, special metrics and related flows
Marisa Fernández, Anna Fino, Alberto Raffero
We review results about -structures in relation to the existence of special metrics, such as Einstein metrics and Ricci solitons, and the evolution under the Laplacian flow on…
On SO(3)-bundles over the Wolf spaces
Marisa Fernández, Jonatan Sánchez, Vicente Muñoz
We study the formality of the total space of principal SU(2) and SO(3)-bundles over a Wolf space, that is a symmetric positive quaternionic Kähker manifold. We apply this to conclu…
Laplacian coflow on the 7-dimensional Heisenberg group
Leonardo Bagaglini, Marisa Fernández, Anna Fino
We study the Laplacian coflow and the modified Laplacian coflow of -structures on the -dimensional Heisenberg group. For the Laplacian coflow we show that the solution is a…
Balanced Hermitian metrics from SU(2)-structures
Marisa Fernández, Adriano Tomassini, Luis Ugarte +1
We study the intrinsic geometrical structure of hypersurfaces in 6-manifolds carrying a balanced Hermitian SU(3)-structure, which we call {\em balanced} SU(2)-{\em structures}. We…
Contact 5-manifolds with SU(2)-structure
Luis C. de Andrés, Marisa Fernández, Anna Fino +1
We consider 5-manifolds with a contact form arising from a hypo structure, which we call \emph{hypo-contact}. We provide conditions which imply that there exists such a structure o…
