Characterization of symmetries of contact Hamiltonian systems
Federico Zadra, Marcello Seri
This paper explores the relationship between Cartan symmetries, dynamical similarities, and dynamical symmetries in contact Hamiltonian mechanics. By introducing an alternative dec…
A Magnetic Pseudodifferential Calculus for Operator-Valued and Equivariant Operator-Valued Symbols
Giuseppe De Nittis, Max Lein, Marcello Seri
In this monograph we develop magnetic pseudodifferential theory for operator-valued and equivariant operator-valued functions and distributions from first principles. These have fo…
The flow method for the Baker-Campbell-Hausdorff formula: exact results
Federico Zadra, Alessandro Bravetti, Angel Alejandro García-Chung +1
Leveraging techniques from the literature on geometric numerical integration, we propose a new general method to compute exact expressions for the BCH formula. In its utmost genera…
The Problem of Two Fixed Centers: Bifurcation Diagram for Positive Energies
Marcello Seri
We give a comprehensive analysis of the Euler-Jacobi problem of motion in the field of two fixed centers with arbitrary relative strength and for positive values of the energy. The…
Resonances in the Two-Centers Coulomb Systems
Marcello Seri, Andreas Knauf, Mirko Degli Esposti +1
We investigate the existence of resonances for two-centers Coulomb systems with arbitrary charges in two dimensions, defining them in terms of generalised complex eigenvalues of a…
