WebNov 5, 2016 · In the 1970s, following in the wake of Stephen Smale, he became one of the major figures in developing the Theory of Hyperbolic Dynamics and Structural Stability. This volume presents a selection of Jacob Palis' mathematical contributions, starting with his PhD thesis and ending with papers on what is widely known as the Palis Conjecture. WebJan 1, 2013 · In fact, Palis put forward a stronger conjecture asserting that typically each minimal attractor supports a unique SRB measure 2 μ that governs behavior of …
WebIn particular, this answers positively Palis’s conjecture for the quadratic family. 0.4. Unimodal maps. Another reason to deal with the quadratic family is that it seems to open the doors to the understanding of unimodal maps. Its universal behavior was first realized in the topological sense, with Milnor- Thurston theory. WebJan 31, 2024 · Homoclinic tangencies and singular hyperbolicity are involved in the Palis conjecture for vector fields. Typical three dimensional vector fields are well understood by recent works. We study the dynamics of higher dimensional vector fields that are away from homoclinic tangencies. More precisely, we prove that for any dimensional vector field that …

WebThe conjectures by Palis and Bonatti have lead to the study of systems away from homoclinic tangencies and/or heterodimensional cycles. In the C1topology, a di eomorphism (or a vector eld) is said to be away from homoclinic tangencies if every system in a C1neighborhood exhibits no homoclinic tangency.
