Institute of Mathematics and Scientific Computing, University of Graz, NAWI Graz, 8010Graz, Austria.

A nonlinear Poisson-Boltzmann equation with inhomogeneous Robin type boundary conditions at the interface between two materials is investigated. The model describes the electrostatic potential generated by a vector of ion concentrations in a periodic multiphase medium with dilute solid particles. The key issue stems from interfacial jumps, which necessitate discontinuous solutions to the problem. Read More

Dynamics of populations with age-difference and diffusion: localization.

Authors:
G E Hernandez

Appl Anal 1988 ;29:143-63

"In this paper we study the behavior of the solutions of the Gurtin-MacCamy model for the dynamics of populations with [spatial] diffusion and age-dependence. We give sufficient conditions on the birth and death modules for the population to remain localized in a fixed interval or to ultimately cover all the domain." Read More
