Fs. Dzheparov et Ve. Shestopal, ASYMPTOTICALLY EXACTLY SOLVABLE MODELS OF RANDOM-WALKS AND OSCILLATIONS IN DISORDERED-SYSTEMS, JETP letters, 60(3), 1994, pp. 182-185
Some new, asymptotically exactly solvable models of random walks and o
scillations in disordered systems are proposed. ''Asymptotically'' her
e means after a long time. Some of the new models are multidimensional
. One-dimensional random walks with a nontrivial unit cell and 2D osci
llations in a simple 2D lattice are examined in detail. A general meth
od for constructing models of this sort is formulated. (C) 1994 Americ
