arXiv:0903.4993
Abstract
Fix a smooth function $Φ: [l,r] \to \bb R$, defined on some interval of $\bb R$, such that . We prove that the evolution, on the diffusive scale, of the empirical density of exclusion processes in $\bb Z^d$, with conductances given by special class of functions , is described by the weak solutions of the non-linear parabolic partial differential equation . We also derive some properties of the operator .
