Discrete flux and velocity fields of probability and their global maps in reaction systems
Discrete flux and velocity fields of probability and their global maps in reaction systems
Stochasticity plays important roles in reaction systems. Vector fields of probability flux and velocity characterize time-varying and steady-state properties of these systems, including high probability paths, barriers, checkpoints among different stable regions, as well as mechanisms of dynamic switching among them. However, conventional fluxes on continuous space are ill-defined and …
