The coalgebra symmetry and the superintegrable discrete-time systems
Giorgio Gubbiotti, Danilo Latini
In this paper, we classify all the variational discrete-time systems in quasi-standard form in degrees of freedom admitting coalgebra symmetry with respect to the generic reali…

Discrete integrable systems and random Lax matrices
Massimo Gisonni, Tamara Grava, Giorgio Gubbiotti +1
We study properties of Hamiltonian integrable systems with random initial data by considering their Lax representation. Specifically, we investigate the spectral behaviour of the c…
