We review results of two previous papers on the asymptotic behavior of finite
connection probabilities in three or more dimensions for Bernoulli percolation and
the Fortuin–Kasteleyn random-cluster model. In the introduction, we prove a
multidimensional renewal theorem that is needed for these results and previous
results on Ornstein–Zernike behavior; the proof is significantly simpler than that
originally derived by Doney (1966) and those of other subsequent works on this
subject.
