摘要:We consider the weighted ergodic optimization problem of a class of dynamical systems. We show that once system satisfies both the Anosov shadowing property (ASP) and the Mane-Conze-Guivarc’h-Bousch property (MCGBP), the minimizing measures of generic Holder observations are uniquely supported on a periodic orbit. Moreover, the above conclusion holds for C^1 observations. Note that a broad class of classical dynamical systems satisfy both ASP and MCGBP, which includes Axiom A attractors, Anosov dieomorphisms and uniformly expanding maps. Therefore, the open problem proposed by Yuan and Hunt since 1999 is completely solved consequentially.

摘要:We consider the weighted ergodic optimization problem for non-degenerate Axiom A attractors of a C^2 flow on a compact smooth manifold. The main result obtained in this paper is that for generic observables from Holder function spaces and C^1 function space, the minimizing measures are uniquely supported on a periodic orbit.
