Exact Hausdorff measures and fine geometry of collisions of independent Markov processes

Ryoichiro Noda

We study the fine geometry of collision measures associated with independent Markov processes on a common metric measure space. These measures are natural space-time random measure…

Convergence of space-time occupation measures of stochastic processes and its application to collisions

Ryoichiro Noda

We introduce a new perspective on positive continuous additive functionals (PCAFs) of Markov processes, which we call space--time occupation measures (STOMs). This notion provides…

Generalized Kac's moment formula for positive continuous additive functionals of Markov processes

Naotaka Kajino, Ryoichiro Noda

We establish a formula for moments of certain random variables involving positive continuous additive functionals (PCAFs) of standard processes which have absolutely continuous tra…

Continuity of the Revuz correspondence under the absolute continuity condition

Ryoichiro Noda

In this paper, we consider standard processes that admit dual processes and satisfy the absolute continuity condition, i.e., processes possess transition densities. For such proces…

Aging and sub-aging for Bouchaud trap models on resistance metric spaces

Ryoichiro Noda

In this paper, we prove that if a sequence of electrical networks converges in the local Gromov-Hausdorff topology and satisfies a non-explosion condition, then the associated Bouc…

Scaling limits of discrete-time Markov chains and their local times on electrical networks

Ryoichiro Noda

We establish that if a sequence of electrical networks equipped with conductance measures converges in the local Gromov--Hausdorff-vague topology and satisfies certain non-explosio…
