Query: Asymptotic Expansions for Stationary Distributions of Nonlinearly
  Perturbed Semi-Markov Processes. I   New algorithms for construction of asymptotic expansions for stationary
distributions of nonlinearly perturbed semi-Markov processes with finite phase
spaces are presented. These algorithms are based on a special technique of
sequential phase space reduction, which can be applied to processes with an
arbitrary asymptotic communicative structure of phase spaces. Asymptotic
expansions are given in two forms, without and with explicit bounds for
remainders.
