Singular Shocks in a Chromatography Model [PDF]
Journal of Mathematical Analysis and Applications, volume 439,
issue 2, year 2016, pages 766-797, 2015 We consider a system of two equations that can be used to describe nonlinear chromatography and produce a coherent explanation and description of the unbounded solutions (singular shocks) that appear in M. Mazzotti's model. We use the methods of Geometric Singular Perturbation Theory, to show existence of a viscous solution to Dafermos-DiPerna ...
