The Henon-Heiles system defined on Lie-algebraically deformed Galilei space-time

In this article we provide the Henon-Heiles system defined on Lie-algebraically deformed nonrelativistic space-time with the commutator of two spatial directions proportional to time. Particularly, we demonstrate that in such a model the total energy is not conserved and for this reason the role of control parameter is taken by the initial energy value $E_{0,{\rm tot}} = E_{{\rm tot}}(t=0)$. Besides, we show that in contrast with the commutative case, for chosen values of deformation parameter $\kappa$, there appears chaos in the system for initial total energies $E_{0,\mathrm{t}\mathrm{o}\mathrm{t}}$ below the threshold $E_{0,\mathrm{t}\mathrm{h}}=1\mathrm{/}6$.
