%0 Journal Article %T Fokker-Planck Equation For The Density Of A Diffusion Process In A Regular Open Set %V 321 %N 9 %P 1251–1256 %X To 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. %J Comptes Rendus De L Academie Des Sciences Serie I-Mathematique %A Chancelier, J.P. %A Delara, M.C. %A Pacard, F. %D 1995
