Criteria for Feller transition functions

Abstract: This paper presents some conditions for the minimal Q -function to be a Feller transition function, for a given q-matrix Q . We derive a sufficient condition that is stated explicitly in terms of the transition rates. Furthermore, some necessary and sufficient conditions are derived of a more implicit nature, namely in terms of properties of a system of equations (or inequalities) and in terms of the operator induced by the q-matrix. The criteria lead to some perturbation results. These results are applied to … Show more

“…We note that Li and Li [97,Theorem 6.2(i)] show that if, under the conditions of this theorem, S abs is finite is replaced by the weaker condition lim i→∞ a i = 0, then divergence of (41) is sufficient for asymptotic remoteness, and hence, by Theorem 9, for the existence of a quasi-stationary distribution.…”

“…Explosion might occur for ∂ = ∅ with probability less than one for CTMCs with nonpolynomial transition rates [25]. Reuter's criterion and its generalizations provide necessary and sufficient conditions for explosivity (with positive probability) for general CTMCs in terms of convergence or divergence of a series [10,22,30], but they are not easy to check. In comparison, for CTMCs with polynomial transition rates, Theorem 3.1 provides an explicit and checkable necessary and sufficient condition.…”

“…In contrast, this might occur with non-polynomial transition rates [36]. Reuter's criterion and its generalizations provide necessary and sufficient conditions for explosivity for general CTMCs [33,45], though they are not easy to check. In comparison, for CTMCs with polynomial transition rates (and d = 1), Theorem 4.1 provides an explicit necessary and sufficient condition.…”
