Presentation

The project aims, firstly, at solving several concrete questions in the modern theory of
conservation laws and related convection-diffusion problems. These questions are concerned with actual techniques
of nonlinear analysis (some of the questions seemed not accessible only a few years ago) ; they originate from
recently identified of from long-standing important applications. The Tasks are all relevant of the
domains of expertise of one of the members of the project and at the same time,
there is a strong connection to at least one of the other members
and to our national and international collaborations.

The second goal is to make advance our understanding of the theory and the crucial tools
(including the most modern ones) for analysis of conservation laws and related nonlinear PDEs.
Indeed, the questions we have selected are representative of several fundamental issues relevant to the problems in hand, such as :
notions of solution and well-posedness ; analysis of non-local terms in conservation laws ; cooperation of
semigroups in evolution equations ; convection-diffusion problems of mixed type ;
boundary and interface problems for conservation laws ;
(ir)regularity and qualitative behaviour of solutions ; converging and efficient numerical approximations.

The scientific program is divided into eight main parts :

• Triangular systems of conservation laws
• Fractionnal conservation laws and convection-diffusion equations
• Viscoelasticity system with memory
• Conservation laws with non local fluxes
• Solution profiles for general conservation laws with dissipative source terms
• Simple 1D and 2D fluide-particule interaction models
• Relativistic heat equation
• Initiation to control of hyperbolic conservation laws

A detailed description of these tasks is available here.
