Approximate and exact solutions of intertwining equations through random spanning forests
Luca Avena, Fabienne Castell, Alexandre Gaudillière +1
For different reversible Markov kernels on finite state spaces, we look for families of probability measures for which the time evolution almost remains in their convex hull. Motiv…
