Feedback Integrators for Mechanical Systems with Holonomic Constraints
Sensors, 2022 The feedback integrators method is improved, via the celebrated Dirac formula, to integrate the equations of motion for mechanical systems with holonomic constraints so as to produce numerical trajectories that remain in the constraint set and preserve ...

First Integrals and Symmetries of Nonholonomic Systems
Archive for Rational Mechanics and Analysis, 2022 AbstractIn nonholonomic mechanics, the presence of constraints in the velocities breaks the well-understood link between symmetries and first integrals of holonomic systems, expressed by Noether’s Theorem. However, there is a known special class of first integrals of nonholonomic systems generated by vector fields tangential to the group orbits, called

A Review of Matrix SIR Arino Epidemic Models
Mathematics, 2021 Many of the models used nowadays in mathematical epidemiology, in particular in COVID-19 research, belong to a certain subclass of compartmental models whose classes may be divided into three “(x,y,z)” groups, which we will call respectively “susceptible/

First Integrals of Differential Operators from SL(2,ℝ) Symmetries
Mathematics, 2020 The construction of first integrals for SL(2,R)-invariant nth-order ordinary differential equations is a non-trivial problem due to the nonsolvability of the underlying symmetry algebra sl(2,R).

On a Class of Integrable Systems with a Cubic First Integral [PDF]
Communications in Mathematical Physics, 2010 A few years ago Selivanova gave an existence proof for some integrable models, in fact geodesic flows on two dimensional manifolds, with a cubic first integral. However the explicit form of these models hinged on the solution of a nonlinear third order ordinary differential equation which could not be obtained.
