We also prove positivity and contractivity of the corresponding semigroup. This results in a description of a stochastic process moving according to classical diffusion in one part of ΩΩ, where jumps are allowed through the rest of ΩΩ.en1424-31992015486987835Hxx35J7047A0747D0660J45Journal Article10.1007/s00028-015-0284-4Other
