Giovanni Bazzoni, Marco Freibert, Adela Latorre +1
We show that complex symplectic structures need not be preserved under small deformations, and we find sufficient conditions for this to happen. We study various cohomologies of co…

Torsion-free -structures on almost Abelian solvmanifolds
Marco Freibert
In this article, we provide a general set-up for arbitrary linear Lie groups which allows to characterise the almost Abelian Lie algebras admittin…

Generalised Einstein metrics on Lie groups
Vicente Cortés, Marco Freibert, Mateo Galdeano
We continue the systematic study of left-invariant generalised Einstein metrics on Lie groups initiated in arXiv:2206.01157. Our approach is based on a new reformulation of the cor…
