| Abstract: | We show how to construct integral results for the multi-dimensional nonlinear diffusion equation  c/t= ·(D(c)c) and for some generalisations of this. For appropriate boundary conditions these become integral invariants. An application of these results to determining the large-time behaviour of some radially symmetric problems is indicated. |
