Query: Optimal detection of a change-set in a spatial Poisson process   We generalize the classic change-point problem to a "change-set" framework: a
spatial Poisson process changes its intensity on an unobservable random set.
Optimal detection of the set is defined by maximizing the expected value of a
gain function. In the case that the unknown change-set is defined by a locally
finite set of incomparable points, we present a sufficient condition for
optimal detection of the set using multiparameter martingale techniques. Two
examples are discussed.
