## Approximate solutions of scalar conservation laws

29 Jul 2016  ·  Perepelitsa Misha ·

We study compactness properties of time-discrete and continuous time BGK-type schemes for scalar conservation laws, in which microscopic interactions occur only when the state of a system deviates significantly from an equilibrium distribution. The threshold deviation, $\epsilon,$ is a parameter of the problem... In the vanishing relaxation time limit we obtain solutions of a conservation law in which flux is pointwisely close (of order $\epsilon$) to the flux of the original equation and derive several other properties of such solutions, including an example of approximate solution to a shock for Burger's equation. read more
