Abstract
Different diffusion processes can be defined on random networks like the infinite incipient clusters at percolation threshold. The long-time behaviour of two such processes is shown to be the same. In particular the mean-square displacements and the autocorrelation function scale with the same exponents in the two cases.Keywords
