Ballesteros Castañeda, Ángel Campoamor Stursberg, Rutwig Fernandez Saiz, Eduardo Herranz, F.J. Lucas Veguillas, Javier de 2018 Producción Científica Based on a recently developed procedure to construct Poisson-Hopf deformations of Lie–Hamilton systems, a novel unified approach to nonequivalent deformations of Lie–Hamilton systems on the real plane with a Vessiot–Guldberg Lie algebra isomorphic to sl(2) is proposed. This, in particular, allows us to define a notion of Poisson–Hopf systems in dependence of a parameterized family of Poisson algebra representations. Such an approach is explicitly illustrated by applying it to the three non-diffeomorphic classes of sl(2) Lie–Hamilton systems. Our results cover deformations of the Ermakov system, Milne–Pinney, Kummer–Schwarz and several Riccati equations as well as of the harmonic oscillator (all of them with t-dependent coefficients). Furthermore t-independent constants of motion are given as well. Our methods can be employed to generate other Lie–Hamilton systems and their deformations for other Vessiot–Guldberg Lie algebras and their deformations. application/pdf http://uvadoc.uva.es/handle/10324/33632 eng A unified approach to Poisson-Hopf deformations of Lie-Hamilton systems based on sl(2) info:eu-repo/semantics/article TEXT UVaDOC.
