Fokker-Planck Equation For The Density Of A Diffusion Process In A Regular Open SettextjournalArticleChancelierJ.P.autDelaraM.C.autPacardF.autTo give physical meaning to the boundary conditions of parabolic partial differential equation, we introduce a diffusion process in some open set, with different boundary conditions (elastic or non-elastic reflection, stopping) and we give the equation satisfied by the density.journal3219125112561995continuingComptes Rendus De L Academie Des Sciences Serie I-Mathematique
