“…Nonetheless, we show that it is still possible to prove the existence of chaotic dynamics for the associated Poincaré map via the LTMs technique dealing with a different geometrical configuration for orbits in the phase plane, in agreement with the results obtained in other contexts e.g. in [9,38]. Regarding the nonisochronicity of the centers, it was proven in [48,49] that the period of the orbits increases with the energy level in the settings that we are going to analyze.…”

“…Namely, as shown in different contexts e.g. in [9,38], a geometrical configuration connected with LTMs may be obtained even when the center position is not affected by a variation of a certain parameter, as long as the latter suitably influences the shape of the orbits. We show two such frameworks in Figures 6 and 7.…”

“…Example 1. We take α = 0.02, β = 0.01, χ = 0.7, ρ = 0.6, σ (I) = 3, σ (I I) = 2.5, c = 0.45, η = 0.3, δ = 1, µ = 1.2 and recall (15), System (MI) has a center in P (I) = (0.141, 0.167) while System (MI I) has a center in P (I I) = (0.170, 0.167).…”

“…We stress, however, that the same assumption about a periodic variation between two different values made on any other model parameter would produce analogous results in terms of generated dynamics, since all parameters influence the center position (We remark that this is a sufficient, albeit not necessary, condition in order to apply the LTMs method whenever we deal with a nonisochronous center, as long as the switching times between the regimes described by the two different parameter values are large enough. As shown, for example, in [12,15], the LTMs technique can be used even when, in consequence of the periodic perturbation of one of the model parameters, the center position does not vary, but the shape of the orbits is modified in a suitable manner).…”

“…A broad but somewhat fuzzy distinction can be made between two groups of topological tools. One class consists of those devices that provide existence results directly on the grounds of how the involved functions interact with the topology of the space they operate upon; examples in this group are Brouwer or Schauder or Kakutani fixed point theorems [22,31,32], the Ważewski theorem [33,34] or the Birkhoff twist-map theorem [35][36][37][38]. A second group constitutes more complex constructions that attach some invariant to the map and then relate it to topological properties of the space.…”
