Rate-induced tipping in a solvable model with the Allee effect

Hidekazu Yoshioka

We present a novel exactly solvable ordinary differential equation model for rate-induced tipping: a dynamic phenomenon of dynamical systems where a time-dependent parameter trigge…

Non-negative diffusion bridge of the McKean-Vlasov type: analysis of singular diffusion and application to fish migration

Hidekazu Yoshioka

The objective of this paper is to provide a new mathematical tool for fish migration that has not been studied well. McKean-Vlasov stochastic differential equations (MVSDEs) have b…

Theoretical and computational investigations of superposed interacting affine and more complex processes

Hidekazu Yoshioka

We theoretically and computationally investigate long-memory processes based on the Markovian lifts of affine jump-diffusion processes. A nominal superposition process consisting o…

Superposition of interacting stochastic processes with memory and its application to migrating fish counts

Hidekazu Yoshioka

Stochastic processes with long memories, known as long memory processes, are ubiquitous in various science and engineering problems. Superposing Markovian stochastic processes gene…

A mean field Jacobi process for modeling sustainable tourism

Hidekazu Yoshioka

A mean field Jacobi process governing the dynamics of the travel demand of agents is formulated and its application to sustainable tourism is investigated both mathematically and c…
