My main research interests are differential (super)geometry and its applications to mathematical physics. I am particularly interested in symplectic, Poisson, contact, Jacobi, and similar geometric structures, as well as their applications to dynamical systems.
In my doctoral dissertation, The geometry of dissipation (September 2024),
I considered different geometric frameworks for modelling non-conservative dynamics, with a special emphasis on the aspects related to the symmetries and integrability of these systems. More specifically, I explored three classes of geometric frameworks modeling dissipative systems: systems with external forces, contact systems, and systems with impacts.
In a broad sense, my recent research has been mainly concerned with coordinates in which different geometric structures have a canonical form. On the one hand, I have been working on a notion of complete integrability for contact Hamiltonian dynamics. Together with L. Colombo, M. de León, and M. Lainz, we proved a Liouville-Arnold theorem for contact Hamiltonian systems, leading to action-angle coordinates in which both the contact form and the Hamiltonian dynamics have a canonical expression. On the other hand, together with J. Grabowski, we have been investigating homogeneous one-forms on graded (super)manifolds, constructing homogeneous coordinates in which the differential form has a canonical expression. Both lines of research are in fact connected, as our approach to completely integrable contact systems is based on the one-to-one correspondence between contact and homogeneous symplectic manifolds.
I plan to continue my research line on the integrability of non-conservative dynamical systems by focusing on almost-symplectic Hamiltonian dynamics (i.e., the differential form on the phase space is non-degenerate but no longer closed). I shall pursue this goal in collaboration with L. Colombo and N. Sansonetto. Our goal is to understand the notions of integrable system, action-angle coordinates, etc. in this framework, which is a natural generalisation of Hamiltonian dynamics on a symplectic manifold. Once we understand these foundations, we would like to apply our theory to studying the integrability of non-holonomic systems. Such systems not only have a rich geometry, but also have remarkable importance in applications to engineering such as drones or robotics.
Our results concerning homogeneous forms on graded (super)manifolds could have applications in several areas of classical and graded differential geometry. In particular, we plan to study their relation with VB-groupoids and their homogeneous cohomology. The structure of a vector bundle (VB) on a manifold can be uniquely determined by a suitable action of the multiplicative group of real numbers on its total space. Roughly speaking, this means endowing the total space with a grading such that the linear coordinates have degree 1, and the basic coordinates have degree 0. In particular, this leads to a quite simple and natural definition of a VB-groupoid. Furthermore, we would like to study the canonical form for other homogeneous geometric structures on graded (super)manifolds, including a Weinstein splitting theorem for homogeneous Poisson manifolds.
