Decay of Correlations for Partially Hyperbolic Skew-Products

We develop a technique based on sectional transfer operators and the regularity of their fixed points to study rates of correlation decay for partially hyperbolic skew-products.

To illustrate the range of applicability of this technique, we apply it to a family of Viana like maps with non-uniformly contracting fibres, a family of skew-product maps with non-uniformly expanding base dynamics and to a generalised family of heterochaos baker maps.

The latter partially hyperbolic systems have recently been an active topic of research due to their connection with the Dyck shift.
