We study the topological dynamics of H\'enon maps. For a parameter set generalizing the Benedicks-Carleson parameters (the Wang-Young parameter set) we obtain the following: The pruning front conjecture (due to Cvitanovi\'c); A kneading theory (realizing a conjecture by Benedicks and Carleson); A classification: two H\'enon maps are conjugate on their strange attractors if and only if their sets of kneading sequences coincide, if and only if their folding patterns coincide. The folding pattern is a single sequence of 0s and 1s, which allows to distinguish two nonconjugate H\'enon attractors in finitely many steps. The classification result relies on further development of the authors' recent inverse limit description of H\'enon attractors in terms of densely branching trees.

  1. Critical set for surface diffeomorphisms revisited

    math.DS 2026-01 conditional novelty 6.0 of 10

    Introduces an intrinsic critical set for surface diffeomorphisms and shows, under 'far-from-homotheties', that it is empty exactly when the invariant set has a dominated splitting.

  2. A Priori Bounds for H\'enon-like Renormalization

    math.DS 2024-11 conditional novelty 6.0 of 10

    Regularly renormalizable Hénon-like maps with bounded combinatorics have uniformly controlled stretching of horizontal curves, so their one-dimensional profiles are precompact.
