Duality and hidden symmetries for time-inhomogeneous Markov processes
Abstract
We study the notion of duality in the setting of time-inhomogeneous Markov processes. We define duality with time-dependent duality functions. We establish the connection between duality and time-dependent symmetries and intertwinings. We illustrate the abstract results with examples from interacting particle systems and diffusion processes.
