Let the phase space of a stochastic process be a metric measurable space. At time t, denote the probability distribution of a stochsstic process with the initial distribution φ by m(t,φ,·). We assume that the family of probability measures {m(t, φ,·), t≥0} satisfies the semi-group property. Consider the epuation of the one-parameter measure family: φ(t+s,·)=m(s, φ(t), ·), t≥0, s≥0. φ(0,·)=φ_0(·). There exists unique family of solution measure for this equation. In this paper, we discuss some properties of this...

Let the phase space of a stochastic process be a metric measurable space. At time t, denote the probability distribution of a stochsstic process with the initial distribution φ by m(t,φ,·). We assume that the family of probability measures {m(t, φ,·), t≥0} satisfies the semi-group property. Consider the epuation of the one-parameter measure family: φ(t+s,·)=m(s, φ(t), ·), t≥0, s≥0. φ(0,·)=φ_0(·). There exists unique family of solution measure for this equation. In this paper, we discuss some properties of this measure family. In the second section, the invariance theorem is proved after several lemmas are established. On the time interval [0, ∞), we prove that the limit set of {m(t, φ),·), t≥0} is a non-empty, weakly bounded and weakly compact invariant measure set under some conditions. The proof of this theorem is simpler and the conditions are weaker than those given by Kushner [1]. In the third section, we consider a time-homogeneous Markov process associated wilh a stochastic continuous transition function. We prove that there are only three posaible cases for the solution of the measure equation: the equilibrium measure or the family of periodic measures from certain moment on, or the measures of the solution are different from each other.

设随机过程的相空间为距离可测空间,以m(t,φ,·)表示初始分布为φ的随机过程在时刻t的概率分布,假定概率测度族{m(t,φ,·);t≥0}具有半群性。考虑单参数测度族方程: φ(t+s,·)=m(s,φ(t),·), t≥0,s≥0φ(0,·)=φ_0(·)此方程存在唯一的解测度族。本文讨论了此测度族的若干性质。§2中证明了在某些条件下,在时问区间[0,∞)上,解测度族的极限集是非空、弱有界、弱紧的不变测度集。我们简化了Kushner[1]1972年的证明並减弱了[1]中不变集定理的假设条件。这时,不变集的支柱集的闭包是过程样本轨道的稳定集(按概率意义)。在§3中,考虑齐次马尔柯夫过程,当过程的转移函数为随机连续时,证明了测度方程的解只有三种可能:从某时刻起为平衡测度或从某时刻起为周期测度族或解测度族中任意二个概率测度均不相同。

In this paper we consider the system where x is a n-vector, A(t) is a n ×n matrix function, which is bounded and continuous in t. Martin discussed the generalized exponential dichotomies in[1]. we genera- lize the definition of generalized exponential dichotomies given by him. By introducing some new definitions, we establish a invariance theorem, which indicates that the generalized exponential stablity is invariant under a small perturbation for the coefficient matrix. Meanwhile, under some suitable assu- mptions and by means of the Lyapunov's second method we establish the nece- ssary and sufficient condition for the solution of the lineur system that possesses a generalized exponential dichotomy.
