Recent results on closed G-structures
Anna Fino, Alberto Raffero
We review recent results concerning closed G-structures on seven-dimensional manifolds. In particular, we discuss the construction of examples and some related problems.
Remarks on homogeneous solitons of the G-Laplacian flow
Anna Fino, Alberto Raffero
We show the existence of expanding solitons of the G-Laplacian flow on non-solvable Lie groups, and we give the first example of a steady soliton that is not an extremally Ricc…
Exact -structures on unimodular Lie algebras
Marisa Fernández, Anna Fino, Alberto Raffero
We consider seven-dimensional unimodular Lie algebras admitting exact -structures, focusing our attention on those with vanishing third Betti number $b_3(\mathf…
Special types of locally conformal closed G-structures
Giovanni Bazzoni, Alberto Raffero
Motivated by analogous results in locally conformal symplectic geometry, we study different classes of G-structures defined by a locally conformal closed 3-form. In particular,…
On -structures, special metrics and related flows
Marisa Fernández, Anna Fino, Alberto Raffero
We review results about -structures in relation to the existence of special metrics, such as Einstein metrics and Ricci solitons, and the evolution under the Laplacian flow on…
