F. Baccelli et al., Differentiability of functionals of Poisson processes via coupling - With applications to queueing theory, STOCH PR AP, 81(2), 1999, pp. 299-321
We give some probabilistic conditions based on coupling for a functional of
a Poisson point process to be differentiable in the intensity lambda of th
is process in a neighborhood of the origin. These conditions are exemplifie
d on various queueing theory problems, and compared with other conditions o
f the literature. (C) 1999 Elsevier Science B.V. All rights reserved.
