Abstract
We discuss some recent results concerning Radon measure-valued solutions of the Cauchy–Dirichlet problem for \partial_t u = \Delta\phi(u) . The function \phi is continuous, nondecreasing, with a growth at most powerlike. Well-posedness and regularity results are described, which depend on whether the initial data charge sets of suitable capacity (determined both by the Laplacian and by the growth order of \phi ), and on suitable compatibility conditions at \pm\infty .
