Topological entropy for countable Markov shifts and Exel--Laca algebras
Yuta Michimoto, Yushi Nakano, Hisayoshi Toyokawa +1
We show that the (Gurevich) topological entropy for the countable Markov shift associated with an infinite transition matrix coincides with the non-commutative topological entr…
Finitude of physical measures for random maps
Pablo G. Barrientos, Fumihiko Nakamura, Yushi Nakano +1
For random compositions of independent and identically distributed measurable maps on a Polish space, we study the existence and finitude of absolutely continuous ergodic stationar…
Observable Lyapunov irregular sets for planar piecewise expanding maps
Yushi Nakano, Teruhiko Soma, Kodai Yamamoto
For any integer with , we present a one-parameter family of 2-dimensional piecewise expanding maps such that each has an ob…
Arcsine law for random dynamics with a core
Fumihiko Nakamura, Yushi Nakano, Hisayoshi Toyokawa +1
In their recent paper [8], G.Hata and the fourth author first gave an example of random iterations of two piecewise linear interval maps without (deterministic) indifferent periodi…
