Helix surfaces for Berger-like metrics on the anti-de Sitter space
Giovanni Calvaruso, Irene I. Onnis, Lorenzo Pellegrino +1
We consider the Anti-de Sitter space equipped with Berger-like metrics, that deform the standard metric of in the direction of the hyperbolic Hopf…
Parallel and totally geodesic hypersurfaces of non-reductive homogeneous four-manifolds
Giovanni Calvaruso, Reinier Storm, Joeri Van der Veken
We classify totally geodesic and parallel hypersurfaces of four-dimensional non-reductive homogeneous pseudo-Riemannian manifolds.
Ricci solitons on low-dimensional generalized symmetric spaces
Giovanni Calvaruso, Eugenia Rosado
We consider three- and four-dimensional pseudo-Riemannian generalized symmetric spaces, whose invariant metrics were explicitly described in [15]. While four-dimensional pseudo-Rie…
From almost (para)-complex structures to affine structures on Lie groups
Giovanni Calvaruso, Gabriela P. Ovando
Let denote a semidirect product Lie group with Lie algebra , where is an ideal and is a subal…
Symmetries of Lorentzian Three-Manifolds with Recurrent Curvature
Giovanni Calvaruso, Amirhesam Zaeim
Locally homogeneous Lorentzian three-manifolds with recurrect curvature are special examples of Walker manifolds, that is, they admit a parallel null vector field. We obtain a full…
Cosymplectic and -cosymplectic Lie algebras
Giovanni Calvaruso, Antonella Perrone
We completely characterize cosymplectic and -cosymplectic Lie algebras in terms of corresponding symplectic Lie algebras and suitable derivations on them. Several examples are g…
