A combinatorial (inclusion-exclusion) approach to the construction of point processes starting from densities is proposed. A formal sufficient criterion is derived and then applied with positive results to systems of functions having a special product form. Thus, a new class of point processes is de
We consider the lattice of subspaces of an n-dimensional vector space V n over a q Ž . finite field GF q and represent a family of such subspaces by elements of a set X. The q-analog of the principle of inclusion᎐exclusion expresses the size of the union of elements of X representing subspaces of V
We show that the number of satisfying assignments of a k-CNF formula is determined uniquely from the numbers of unsatisfying assignments for clause-sets of size up to log k + 2. This amount of information is also shown to be necessary.
