Löpker and Palmowski have shown conditions under which a [[reversed process|time reversed]] PDMP is a PDMP.<ref>{{Cite journal | last1 = Löpker | first1 = A. | last2 = Palmowski | first2 = Z. | doi = 10.1214/EJP.v18-1958 | title = On time reversal of piecewise deterministic Markov processes | journal = Electronic Journal of Probability | volume = 18 | year = 2013 | arxiv = 1110.3813| s2cid = 1453859 }}</ref> General conditions are known for PDMPs to be stable.<ref>{{Cite journal | last1 = Costa | first1 = O.

Their work opens the way to any application using densities of trajectory. (For instance, they used the density of a trajectories to perform [[importance sampling]], this work was further developed by Chennetier and Al.<ref>{{cite arxivarXiv| last1 = Chennetier | first1 = G. | title =Adaptive importance sampling based on fault tree analysis for piecewise deterministic Markov process | year = 2022 | arxivclass = stat.CO | eprint = 2210.16185 }}</ref> to estimate the reliability of industrial systems.)
