Abstract
In the context of the study of diffusion in disordered media we present an alternative way to obtain the Terwiel cumulants expansion. Our approach sta rts from a formal solution of the master equation (ME) associated with the model of the nearest-neighbour random walk in a one-dimensional disordered chain. We apply our formalism to the analysis of a finite-effective-medium- like approximation.
