Random walks in disordered systems with long-range transitions. Asymptotically exactly solvable models

Random-jump models of transport in disordered systems are studied. They are described by the master equationP=−AξP, whereA is the generator of a spatially and temporally uniform random walk on a regular lattice, ξ is a diagonal operator, and ξ null null null null null null null null null null null null null null null null null xy null null null null null null null null null null null null null null null =ξ null null null null null null null...
