Nearly parallel -manifolds: formality and associative submanifolds
Marisa Fernández, Anna Fino, Alexei Kovalev +1
We construct new examples of non-formal simply connected compact Sasaki-Einstein 7-manifolds. We determine the minimal model of the total space of any fibre bundle over with…
Symplectic half-flat solvmanifolds
Marisa Fernández, Víctor Manero, Antonio Otal +1
We classify solvable Lie groups admitting left invariant symplectic half-flat structure. When the Lie group has a compact quotient by a lattice, we show that these structures provi…
Bianchi type A hyper-symplectic and hyper-Kähler metrics in 4D
Luis C. de Andrés, Marisa Fernández, Stefan Ivanov +3
We present a simple explicit construction of hyper-Kaehler and hyper-symplectic (also known as neutral hyper-Kaehler or hyper-parakaehler) metrics in 4D using the Bianchi type grou…
Quaternionic Kaehler and Spin(7) metrics arising from quaternionic contact Einstein structures
Luis C. de Andrés, Marisa Fernández, Stefan Ivanov +3
We construct left invariant quaternionic contact (qc) structures on Lie groups with zero and non-zero torsion and with non-vanishing quaternionic contact conformal curvature tensor…
