The heterotic G-system on 2-step nilmanifolds endowed with principal torus bundles
Andrei Moroianu, Alberto Raffero, Luigi Vezzoni
We study the geometric heterotic G-system on 7-dimensional 2-step nilmanifolds endowed with principal torus bundles and with a prescribed flat tangent bundle…
The characteristic group of Lie LCP manifolds
Viviana del Barco, Andrei Moroianu
The (reduced) characteristic group of a locally conformally product manifold is obtained by restricting the action of its fundamental group to the non-flat factor of the universal…
The Pestov identity on the frame bundle and associated homogeneous fibrations
Mihajlo Cekić, Thibault Lefeuvre, Andrei Moroianu +1
In this short note, we prove a global Pestov identity on the (orthonormal) frame bundle of a Riemannian manifold and deduce similar identities on associated homogeneous fibrations.…
-structures with parallel skew-symmetric torsion
Andrei Moroianu, Uwe Semmelmann
We classify -dimensional Riemannian manifolds carrying a metric connection with parallel skew-symmetric torsion whose holonomy is contained in , up to naturally re…
Symmetric Killing tensors on almost abelian Lie groups
Renan Berto-Cuevas, Viviana del Barco, Andrei Moroianu
In this work we provide a complete characterization of left-invariant symmetric Killing tensors on almost abelian Lie groups endowed with a left-invariant Riemannian metric. We sho…
Reducible Riemannian manifolds with conformal product structures
Andrei Moroianu, Mihaela Pilca
We study conformal product structures on compact reducible Riemannian manifolds, and show that under a suitable technical assumption, the underlying Riemannian mani\-folds are eith…
