A point process is determinantal with kernel $K$ relative to a specified reference measure if every <correlation function of a point process> is the indicated <determinant>. A rank-$m$ <finite-rank projection kernel> gives an exactly $m$-point process, whose symmetric joint density is $\det[K(x_i,x_j)]/m!$.
