On Gauduchon connections with Kähler-like curvature
Daniele Angella, Antonio Otal, Luis Ugarte +1
We study Hermitian metrics with a Gauduchon connection being "Kähler-like", namely, satisfying the same symmetries for curvature as the Levi-Civita and Chern connections. In partic…
Invariant solutions to the Strominger system and the heterotic equations of motion
A. Otal, L. Ugarte, R. Villacampa
We construct many new invariant solutions to the Strominger system with respect to a 2-parameter family of metric connections in the anomaly cancellation e…
Six dimensional solvmanifolds with holomorphically trivial canonical bundle
Anna Fino, Antonio Otal, Luis Ugarte
We determine the 6-dimensional solvmanifolds admitting an invariant complex structure with holomorphically trivial canonical bundle. Such complex structures are classified up to is…
Paracontact metric structures on the unit tangent sphere bundle
Giovanni Calvaruso, Verónica Martín-Molina
Starting from -natural pseudo-Riemannian metrics of suitable signature on the unit tangent sphere bundle of a Riemannian manifold , we construct a f…
On the Bott-Chern cohomology and balanced Hermitian nilmanifolds
Adela Latorre, Luis Ugarte, Raquel Villacampa
The Bott-Chern cohomology of 6-dimensional nilmanifolds endowed with invariant complex structure is studied with special attention to the cases when balanced or strongly Gauduchon…
The curvature tensor of almost cosymplectic and almost Kenmotsu (κ,μ,ν)-spaces
Alfonso Carriazo, Verónica Martín-Molina
We study the Riemann curvature tensor of (κ,μ,ν)-spaces when they have almost cosymplectic and almost Kenmotsu structures, giving its writing explicitly. This leads to the definiti…
