Fields of covariances on non-commutative probability spaces in finite dimensions
Florio M. Ciaglia, Fabio Di Cosmo, Laura González-Bravo
We introduce the notion of a field of covariances, a contravariant functor from non-commutative probability spaces to Hilbert spaces, as a categorical analogue of statistical covar…
Jacobi algebroids and Jacobi sigma models
Fabio Di Cosmo, Katarzyna Grabowska, Janusz Grabowski
The definition of an action functional for the Jacobi sigma models, known for Jacobi brackets of functions, is generalized to \emph{Jacobi bundles}, i.e., Lie brackets on sections…
On -invariant self-adjoint extensions of the Laplacian on quantum circuits
A. Balmaseda, F. Di Cosmo, J. M. Pérez-Pardo
An analysis of the invariance properties of self-adjoint extensions of symmetric operators under the action of a group of symmetries is presented. For a given group , criteria f…
Some Notes on Dirac operators on the and spheres
Fabio Di Cosmo, Alessandro Zampini
We describe both the Hodge - de Rham and the spin manifold Dirac operator on the spheres and , following the formalism introduced by Kähler, and exhibit a co…
