Cutoff on non-negatively curved chains without symmetric support condition
Kazuki Okamura
We establish a cutoff criterion for finite Markov chains with non-negative Bakry--Émery curvature without assuming that the support of the transition matrix is symmetric. This exte…

Asymptotic estimates for multiple point ranges of transient random walks on graphs
Kazuki Okamura
We study multiple point ranges for random walks on graphs, extending known asymptotic results obtained for random walks on groups. A distinctive feature is that algebraic and trans…

A remark on the comparison of the sum and the maximum of positive random variables
Kazuki Okamura
We disprove a conjecture stated in a recent paper by Arnold and Villasenor concerning the sum and the maximum of independent and identically distributed half-normal random variable…
