从关联状态转移网络的结构得到有限状态空间主方程的长期行为

Obtaining the long-term behavior of Master equations with finite state space from the structure of the associated state transition network

Bernd Fernengel, Barbara Drossel

摘要:

主方程描述了具有离散状态空间的系统的概率的时间演化。这种时间演化在很长一段时间内接近一个通常取决于初始概率分布的稳态。在数学文献中,定态是唯一的条件通常作为附加在更全面的理论之后的注释给出。我们提供了一个直接和完整的推导的必要和充分的标准时,这种稳定状态是唯一的。我们把这个问题转化为图论的语言,并表明,有一个一对一的对应关系的最小吸收集内的状态转换网络和线性独立的主方程的稳态。

英文摘要:

The Master equation describes the time evolution of the probabilities of a system with a discrete state space. This time evolution approaches for long times a stationary state that will in general depend on the initial probability distribution. Conditions under which the stationary state is unique are usually given as remarks appended to more comprehensive theories in the mathematical literature. We provide a direct and complete derivation of a necessary and sufficient criterion for when this steady state is unique. We translate this problem into the language of graph theory and show that there is a one-to-one correspondence between minimal absorbing sets within the state-transition network and linearly independent stationary states of the Master equation.
