Universal Minimal Flow in the Theory of Topological Groupoids
Riccardo Re, Pietro Ursino
In this paper we investigate some connections between Topological Dynamics, the theory of G-Principal Bundles, and the theory of Locally Trivial Groupoids.
PGL(2) actions on Grassmannians and projective construction of rational curves with given restricted tangent bundle
Alberto Alzati, Riccardo Re
We give an explicit parametrization of the Hilbert schemes of rational curves C in P^n having a given splitting type of the restricted tangent bundle from P^n to C. The adopted tec…
Groupoid Quantales: a non étale setting
Alessandra Palmigiano, Riccardo Re
It is well known that if G is an étale topological groupoid then its topology can be recovered as the sup-lattice generated by G-sets, i.e. by the images of local bisections. This…
Multiplications of Maximal Rank in the Cohomology of P^1\times P ^1
Salvatore Giuffrida, Renato Maggioni, Riccardo Re
We show that the linear map defined by multiplication with a general bi-homogeneous form between two bi-graduated pieces of the first cohomology of a nonsingular quadric in the pro…
