Nous établissons plusieurs propriétés asymptotiques fondamentales des solutions u(⋅,t) des équations d'avection–diffusion du type ut+f(u)x=(a(u)ux)x, x∈R, t>0, aux données initiales dans l'espace de Lebesgue Lp(R), où 1⩽p<∞.

We state and discuss a number of fundamental asymptotic properties of solutions u(⋅,t) to one-dimensional advection–diffusion equations of the form ut+f(u)x=(a(u)ux)x, x∈R, t>0, assuming initial values u(⋅,0)=u0∈Lp(R) for some 1⩽p<∞.
