| Resumen: | We show some compactness properties of the operator f--u, where u is the solution of the nonlinear diffusion equation ut???(u)=f on (0,T)×? associated with the parabolic boundary conditions ?(u)=0 on (0,T)×?? and u(0,?)=u0(?) on ?, u0 a given function in L1(?). Our results are carried out under the general assumption that ? is a real continuous strictly increasing function satisfying ?(0)=0. |
