We discuss initial value problems and initial boundary value problems for some systems of
partial differential equations appearing in the modelling for the large scale structure …

We derive explicit formulae for spherically symmetric solutions to the system of
multidimensional zero-pressure gas dynamics and its adhesion approximation. The …

The 3-dimensional zero-pressure gas dynamics system appears in the modeling for the
large scale structure formation in the universe. The aim of this paper is to construct …

In this article, we study initial and initial-boundary value problems for a non-strictly
hyperbolic system whose characteristic speed is not smooth and takes values in {-1, 0, 1} …

We construct explicit solutions of a system of two conservation laws with small viscosity in
the quarter plane {(x, t): x> 0, t> 0}, with initial conditions at t= 0 and flux conditions at x= 0 …

We consider a class of kinetic models for which a moment equation has a natural
interpretation. We show that, depending on their velocity field, some models lead to moment …

In this survey article, we discuss a few applications of three successful notions of the product
of distributions (the Colombeau algebra, the method of weak asymptotics and the notion of …
