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…
Formality of 7-dimensional 3-Sasakian manifolds
Marisa Fernández, Stefan Ivanov, Vicente Muñoz
We prove that any simply connected compact 3-Sasakian manifold, of dimension seven, is formal if and only if its second Betti number is . In the opposite, we show an example…
A -dimensional simply connected complex and symplectic manifold with no Kähler metric
Giovanni Bazzoni, Marisa Fernández, Vicente Muñoz
We construct a simply connected compact manifold which has complex and symplectic structures but does not admit Kähler metrics, in the lowest possible dimension where this can happ…
