摘要
本文考虑形如Q=(■)的拟Q-矩阵,其中e1=+∞,且Q_b不要求全稳定。假定存在Q_b过程ψ(λ),记P_(φ(λ))(Q)={(Rλ):(Rλ)为Q过程且_bR(λ)-ψ(λ)}称为由ψ(λ)生成的过程类。本文给出P_(φ(λ))(Q)非空,即由ψ(λ)生成的过程存在的充要条件。
Let Q=(■) be a quasi Q-matrix,where el=+∞,Q_b needn't be totally stable ψ(λ)is a Q_b-Process,written as P_(ψ(λ))(Q)={R(λ):R(λ)is a Q-process and _bR(λ)=ψ(λ)}is called a class of processes generated by ψ(λ).In this paper,We will give the necessary and sufficient conditions for P_(ψ(λ))(Q)are noempty.
