Decay of correlations and normal approximation for nonstationary heterochaos baker maps

Juho Leppänen, Hiroki Takahasi

We study statistical properties of nonstationary compositions of a sequence of heterochaos baker maps. For maps whose central direction is mostly expanding, we establish three main…

The recurrence spectrum for dynamical systems beyond specification

Hiroki Takahasi

We introduce {\it (W')-specification} in terms of language decompositions of subshifts, and show that any recurrence set of a subshift with this property has full Hausdorff dimensi…

Hausdorff dimension of specification for the -shifts

Hiroki Takahasi

Specification is an important concept in dynamical systems introduced by Bowen. Schmeling proved that the set of such that the corresponding -shift has specification is of…

Large deviation principles for periodic points of the Dyck shift

Hiroki Takahasi

We investigate periodic points of the Dyck shift from the viewpoint of large deviations. We establish the level-2 Large Deviation Principle with the rate function given in terms of…

Exponential mixing for heterochaos baker maps and the Dyck system

Hiroki Takahasi

We investigate mixing properties of piecewise affine non-Markovian maps acting on or and preserving the Lebesgue measure, which are natural generalizations of t…

Large deviations of homological growth rates for hyperbolic surfaces

Johannes Jaerisch, Hiroki Takahasi

We perform a large deviations analysis of homological growth rates of oriented geodesics on hyperbolic surfaces. For surfaces uniformized by a wide class of Fuchsian groups of the…
