Nonlinear equations with unbounded heat conduction and integrable data
Résumé
We consider a class of quasi-linear diffusion problems involving a matrix A(t, x, u) which blows up for a finite value m of the unknown u. Stationary and evolution equations are studied for L1 data. We focus on the case where the solution u can reach the value m. For such problems we introduce a notion of renormalized solutions and we prove the existence of such solutions.
