@article{Jansen2012OnTN, title={On the notion(s) of duality for Markov processes}, author={S. Jansen and N. Kurt}, journal={Probability Surveys}, year={2012}, volume={11}, pages={59-120} }

We provide a systematic study of the notion of duality of Markov processes with respect to a function. We discuss the relation of this notion with duality with respect to a measure as studied in Markov process theory and potential theory and give functional analytic results including existence and uniqueness criteria and a comparison of the spectra of dual semi-groups. The analytic framework builds on the notion of dual pairs, convex geometry, and Hilbert spaces. In addition, we formalize the… Expand
