[Theory of kinetic schemes. Random walks]

During special selection of self--functions of states methods of the kinetic scheme theory can be extrapolated on some probability processes. General solutions can be obtained with these methods, for the problem of casual wanderings in manymeric lattices for example. The general result of the work--distribution of average lifetime of a population in states is in the general case determined only by the topology of the scheme and is independent of the form of self-functions of states.
