C1 density of stable ergodicity
A Avila, S Crovisier, A Wilkinson - Advances in Mathematics, 2021 - Elsevier
We prove a C 1 version of a conjecture by Pugh and Shub: among partially hyperbolic
volume-preserving C r diffeomorphisms, r> 1, the stably ergodic ones are C 1-dense. To …

Robust criterion for the existence of nonhyperbolic ergodic measures
J Bochi, C Bonatti, LJ Díaz - Communications in Mathematical Physics, 2016 - Springer
We give explicit C 1-open conditions that ensure that a diffeomorphism possesses a
nonhyperbolic ergodic measure with positive entropy. Actually, our criterion provides the …

Partially hyperbolic dynamics in dimension three
PD Carrasco, F Rodriguez-Hertz… - Ergodic Theory and …, 2018 - cambridge.org
Partial hyperbolicity appeared in the 1960s as a natural generalization of hyperbolicity. In
the last 20 years, there has been great activity in this area. Here we survey the state of the …

Exponential state estimation, entropy and Lyapunov exponents
C Kawan - Systems & Control Letters, 2018 - Elsevier
In this paper we study the notion of estimation entropy established by Liberzon and Mitra.
This quantity measures the smallest rate of information about the state of a system above …
