英文摘要: |
A theorem of Blumentbal; Getoor and McKean (1962) states: Let both X (t) and
X*(t) be Hunt processes, then they have identical hitting distributions if there exists
a continuous random time substitute Z(t) such that X(Z(t) and X*(t) have identical
transition functions.
In this paper an analogous theorem is established for countable homogeneoue
Markov processes with conservative Q-matrix (in general, they are not Hunt processes),and another necessary and sufficient condition is found. |
