摘要：

The one-dimensional diffusion in potentials which have a finite number of jumps in their value and in their derivative is investigated. The jump conditions of the eigenfunctions of the corresponding Fokker-Planck-operator are derived. These conditions are then applied to bistable models, to a metastable model and to a periodic potential model. At least for one model in all these three cases all eigenvalues and eigenfunctions are given analytically. © 1979 Springer-Verlag.
