Non-noise sensitivity for word hyperbolic groups

Ryokichi Tanaka

We show that non-elementary random walks on word hyperbolic groups with finite first moment are not noise sensitive in a strong sense for small noise parameters.

Invariant measures of the topological flow and measures at infinity on hyperbolic groups

Stephen Cantrell, Ryokichi Tanaka

We show that for every non-elementary hyperbolic group, an associated topological flow space admits a coding based on a transitive subshift of finite type. Applications include reg…

Isogeny graphs on superspecial abelian varieties: Eigenvalues and Connection to Bruhat-Tits buildings

Yusuke Aikawa, Ryokichi Tanaka, Takuya Yamauchi

We study for each fixed integer $g \geq 2$ , for all primes $ℓ$ and $p$ with $ℓ \neq = p$ , finite regular directed graphs associated with the set of equivalence classes of $ℓ$ …
