Asymptotically exactly solvable models of random walks and oscillations in disordered systems
Dzheparov F. S., Shestopal V. E.
Some new, asymptotically exactly solvable models of random walks and oscillations in disordered systems are proposed. "Asymptotically" here means after a long time. Some of the new models are multidimensional. One-dimensional random walks with a nontrivial unit cell and 2D oscillations in a simple 2D lattice are examined in detail. A general method for constructing models of this sort is formulated. © 1994 American Institute of Physics.
