Measures of maximal entropy for C∞ three‐dimensional flows
Yuntao Zang
Source abstract
Abstract We prove that every nonsingular flow with positive entropy on a compact three‐dimensional manifold without boundary admits finitely many ergodic measures of maximal entropy. This result extends the notable work of Buzzi–Crovisier–Sarig ( Ann. of Math . 195 (2022), 421–508) on surface diffeomorphisms. Our approach differs by addressing the continuity of Lyapunov exponents and the uniform largeness of Pesin sets for measures of maximal entropy. Furthermore, it provides an alternative proof for the case of surface diffeomorphisms.
