Sumari:	Title screen We expand the symmetry of the open finite-size SO(N ) symmetric spin chain to O(N ). We partition itsspace of states into the eigenspaces of the parity transformations in the flavor space, generating the subgroupZ?(N?1)2 . It is proven that the lowest-energy states in these eigenspaces are nondegenerate and assemblein antisymmetric tensors or pseudotensors. At the valence-bond solid point, they constitute the 2N?1-folddegenerate ground state with fully broken parity-transformation symmetry Режим доступа: по договору с организацией-держателем ресурса
