1-Lefschetz contact solvmanifolds
Adrián Andrada, Agustín Garrone
We study the contact Lefschetz condition on compact contact solvmanifolds, as introduced by B.\ Cappelletti-Montano, A.\ De Nicola and I.\ Yudin. We seek to fill the gap in the lit…
Holonomy of the Obata connection on 2-step hypercomplex nilmanifolds
Adrián Andrada, María Laura Barberis, Beatrice Brienza
We study the holonomy of the Obata connection on 2-step hypercomplex nilmanifolds. By explicitly computing the curvature tensor, we determine the conditions under which the Obata c…
Symplectic solvmanifolds not satisfying the hard-Lefschetz condition
Adrián Andrada, Agustín Garrone
For Lie groups of the form , with even, a result of H. Kasuya shows that if the action is semisimple then any s…
-Einstein Sasakian Lie algebras
Adrián M. Andrada, Simon G. Chiossi, Alberth J. Nuñez
We study -Einstein Sasakian structures on Lie algebras, that is, Sasakian structures whose associated Ricci tensor satisfies an Einstein-like condition. We divide into the cases…
Almost abelian complex nilmanifolds
Adrián Andrada, Romina M. Arroyo, María L. Barberis +2
We show that a complex structure on a nilpotent almost abelian real Lie algebra is unique if it exists. As a consequence, we get full control over the cohomology and deformations o…
