Abstract
We have found the exact ground state for a large class of antiferromag netic spin-1 models with nearest-neighbour interactions on a linear ch ain. All ground-state properties can be calculated. The ground state i s determined as a matrix product of individual site states and has the properties of the Haldane scenario.
