We study the singularity problem for the pairwise distance matrix of a system
of points, as well as generalizations of this problem that are connected with
applications to interpolation theory and with an algebraic approach
to recognition problems. We obtain necessary and sufficient conditions on a system
under which the dimension of the range space of polynomials of bounded degree
over the columns of the distance matrix is less than the number of points
in the system.
Keywords:
pairwise distance matrix, metric, correctness criteria, system of points.
