Abstract
A new representation of the Hubbard model in the Clifford algebra spec ially suited to describe complex many-particle states in simple terms is introduced. The form of the hamiltonian and other relevant observab les in the new representation are discussed and several families of no ntrivial half-filled states are readily obtained.
