摘要
Random fields on Z(+)(d), with long range weak dependence for each coordinate at a time, usually present clustering of high values based on Poisson distributions for positions of the clusters. The asymptotic theory for point processes of exceedances of high values is developed. (C) 2011 Elsevier B.V. All rights reserved.
