Partially dissipative systems in the critical regularity setting, and strong relaxation limit
Partially dissipative systems in the critical regularity setting, and strong relaxation limit
Many physical phenomena may be modeled by first order hyperbolic equations with degenerate dissipative or diffusive terms. This is the case for example in gas dynamics, where the mass is conserved during the evolution, but the momentum balance includes a diffusion (viscosity) or damping (relaxation) term, or, in numerical simulations, …
