Abstract:

We obtain various new well-posedness results for continuity and transport equations, among them an existence and uniqueness theorem (in the class of strongly continuous solutions) in the case of nearly incompressible vector fields, possibly having a blow-up of the $BV$ norm at the initial time. We apply these results (valid in any space dimension) to the $k \times k$ chromatography system of conservation laws and to the $k \times k$ Keyfitz and Kranzer system, both in one space dimension.

Keywords: BV functions, Transport equation, Chromatography system
