摘要：

Carrying out a program proposed by C.N. Yang, we prove that all "regular" (as defined in the paper) Bethe-Ansatz states of the 1-dimensional Hubbard model on a lattice of finite length L are lowest-weight vectors of an SO(4) algebra. Thus new eigenstates can be obtained by acting with the SO(4) raising operators on the Bethe-Ansatz states. In a following publication we will show that the SO(4) structure in combination with the Bethe Ansatz leads to a complete set of eigenfunctions for the 1-dimensional Hubbard model (asymptotically for large but finite lattice lengths L).
