Lattice Structures for Attractors II

Abstract: ABSTRACT. The algebraic structure of the attractors in a dynamical system determine much of its global dynamics. The collection of all attractors has a natural lattice structure, and this structure can be detected through attracting neighborhoods, which can in principle be computed. Indeed, there has been much recent work on developing and implementing general computational algorithms for global dynamics, which are capable of computing attracting neighborhoods efficiently. Here we address the question of wheth… Show more

“…To address the lack of robustness of invariant sets with respect to parameters, another change in perspective is needed. Initiated by C. Conley [37] and developed over the last 40 years [38][39][40][41] the emphasis shifts from invariant sets to positively attracting sets.…”

“…The collection of all attractors in 𝒱 under ℱ is denoted by Att(ℱ) and as discussed in [17, Section 2] is a bounded distributive lattice where 0 := ∅ and 1 = max {𝒜 | 𝒜 ∈ Att(ℱ)}. Furthermore, given 𝒜 0 , 𝒜 1 ∈ Att(ℱ) the lattice operations are defined by…”

“…We show that Inv + (·, ϕ) is spacious (Proposition 5.12) even though in general Inv(·, ϕ) is not (Example 5.11). An important benefit of this approach, that is exploited in future work [11], is that if we develop numerical methods under which Inv + (·, ϕ) or Inv(·, ϕ), restricted to computable neighborhoods, is spacious, then we can guarantee that our numerical methods are capable of capturing the desired algebraic structure of the dynamics. A version of Theorem 1.2 for invertible systems is proved in Robbin and Salamon [14].…”
