Wave interactions and stability of Riemann solutions for a nonautonomous Chromatography-type system of Langmuir isotherm

Richard De la cruz, Rakib Mondal, Wladimir Neves

We investigate the wave interactions and stability of Riemann solutions for a nonautonomous chromatography-type system of Langmuir isotherm with time-dependent damping and flux. Th…

Riemann problem for a nonsymmetric Keyfitz-Kranzer and pressureless gas systems with a time-dependent Coulomb-like friction term

Richard De la cruz, Wladimir Neves

In this paper, we study the Riemann solutions for two systems: the nonsymmetric Keyfitz-Kranzer system and the pressureless system, both of which have a time-dependent Coulomb-like…

On a class of nonautonomous quasilinear systems with general time-gradually-degenerate damping

Richard De la cruz, Wladimir Neves

In this paper, we study two systems with a time-variable coefficient and general time-gradually-degenerate damping. More explicitly, we construct the Riemann solutions to the time-…

Delta shock wave for a hyperbolic system of conservation laws

Richard De la cruz, Juan C. Juajibioy, Juan Galvis +1

We study the one-dimensional Riemann problem for a hyperbolic system of three conservation laws of Temple class. This systems it is a simplification of a recently propose system of…

Asymptotic behavior of global entropy solutions for nonstrictly hyperbolic systems with linear damping

Juan C. Juajibioy, Richard A De la Cruz, Leonardo Rendon

In this paper we investigate the large time behavior of the global weak entropy solutions to the symmetric Keyftiz-Kranzer system with linear damping. It is proved that as t tends…
