Cyclic Phenomena for composition operators on Weighted Bergman Spaces
No full textIn the present paper we give a generalization to the family of Bergman Spaces with Weight , of several results obtained for the Hardy space, concerning the cyclic and hypercyclic behaviour of composition operators induced by a holomorphic self map of the open unit disc
Considerazioni sulla storia degli studi neoaramaici, in A. Bausi - A. Gori - G. Lusini (eds.), Linguistic, Oriental and Ethiopian studies in memory of Paolo Marrassini, Wiesbaden: Harrassowitz, 2015, 273-320
No full textCritical overview of the history of research on Neo-Aramaic, articulated in its dialectal subgroupings, since 1850 to the present, against the background of Semitic linguistics
Two-orbit Kaehler manifolds and Morse Theory
No full textWe deal with compact K\"ahler manifolds acted on by a compact Lie group of isometries, whose complexification K^\C has exactly one open and one closed orbit in . If the -action is Hamiltonian, we obtain results on the cohomology and the -equivariant cohomology of
Remarks on Kähler–Ricci solitons
No full textWe prove that a complex compact manifold endowed with a Ka ̈hler Ricci soliton cannot be isometrically embedded in a complex projective space CP^n in such a way that the Gauss map is rational, unless the metric is Einstein. This applies to hypersurfaces of complex compact homogeneous spaces canonically embedded in CP^n.
We moreover obtain two curvature constraints for invariant Ka ̈hler Ricci solitons on complex manifolds acted on by a compact Lie group with cohomogeneity one
Homogeneous Lagrangian submanifolds
No full textWe characterize isometric actions on compact Kaehler manifolds admitting a Lagrangian orbit, describing under which condition the Lagrangian orbit is unique. We furthermore give the complete classification of simple groups acting on the complex projective space with a Lagrangian orbit, and we give the explicit list of these orbits
Actions of vanishing homogeneity rank on quaternionic-Kaehler projective spaces
No full textWe classify isometric actions of compact Lie groups on quaternionic-K\"ahler projective spaces with vanishing homogeneity rank. We also show that they are not in general quaternion-coisotropic
A Hamiltonian stable minimal Lagrangian submanifold of projective space with non-parallel second fundamental form
No full textIn this note we show that Hamiltonian stable minimal Lagrangian submanifolds of projective space need not have parallel second fundamental form
On deformations of Hamiltonian actions
No full textIn this paper we generalize to coisotropic actions of compact Lie groups a theorem of Guillemin on deformations of Hamiltonian structures on compact symplectic manifolds. We show how one can reconstruct from the moment polytope the symplectic form on the manifold
