Dynamic minimisation of the commute time for a one-dimensional diffusion

Ma. Elena Hernández-Hernández, Saul Jacka

Motivated in part by a problem in simulated tempering (a form of Markov chain Monte Carlo) we seek to minimise, in a suitable sense, the time it takes a (regular) diffusion with in…

Martingale approach to control for general jump processes

Ma. Elena Hernández-Hernández, Saul Jacka, Aleksandar Mijatović

We provide verification theorems (at different levels of generality) for infinite horizon stochastic control problems in continuous time for semimartingales. The control framework…
