An. Dudin et Vi. Klimenok, STATIONARY DISTRIBUTION OF 2-DIMENSIONAL QUASI-TOEPLITZ MARKOV-CHAIN, Automatic control and computer sciences, 32(1), 1998, pp. 11-17
An important class of two-dimensional Markov chains with discrete time
, called quasi-Toeplitz Markov chains, is introduced. These types of c
hains yield an adequate description of the operation of an extraordina
rily broad class of models of information transmission processes in mo
dern information computer networks A sufficient existence condition fo
r the stationary distribution is proved and a linear functional equati
on for the generating vector function of this distribution is obtained
