It is found to be a necessary and sufficient condition for a set of quantum variables x 1 x 2 x n to have a nonzero multilinear quantum operation. It is proved that if no one proper subset of this set satisfies this condition, then a space of all multilinear quantum operations is of dimension n -2
## Abstract A necessary condition for the existence of a circuit of any specified length in a connected planar graph is developed and several applications of this result are given. This necessary condition is a direct generalization of the KosyrevβGrinberg condition for the existence of a Hamiltoni
In this paper we consider designs in polynomial metric spaces with relatively small cardinalities (near to the classical bounds). We obtain restrictions on the distributions of the inner products of points of such designs. These conditions turn out to be strong enough to ensure obtaining nonexistenc
