Summary: We shall be concerned with the problem of determining the quasistationary distributions of an absorbing continuous-time Markov chain directly from the transition-rate matrix $Q$. We shall present conditions which ensure that any finite $\mu$-invariant probability measure for $Q$ is a quasistationary distribution. Our results will be illustrated with reference to birth and death processes. For the entire collection see [Zbl 0848.00021
