The Bowen-Ruelle conjecture predicts that geodesic flows on negatively curved manifolds are exponentially mixing with respect to all their equilibrium states. In a breakthrough in '98, Dolgopyat pioneered a method rooted in the thermodynamic formalism that settled the conjecture for flows satisfying certain strong regularity hypotheses. Soon after, Liverani introduced a more intrinsic refinement of Dolgopyat's method which overcame these regularity limitations while simultaneously producing more precise rates of mixing, albeit at the price of being limited to smooth invariant measures. Despite these important developments, the conjecture remains open in general even for measures of maximal entropy. In this talk, I will report on work in progress where new ideas leveraging inverse theorems in additive combinatorics are introduced to overcome the limitations in Liverani's approach in a concrete algebraic setting.
