Spectral estimates for Ruelle transfer operators with two parameters and applications

Vesselin Petkov, Luchezar Stoyanov

For $C^2$ weak mixing Axiom A flow ${\varphi }_t:M⟶M$ on a Riemannian manifold $M$ and a basic set $\Lambda$ for ${\varphi }_t$ we consider the Ruelle transfer operator $L_{f-s\tau +zg}$…
