摘要：

Remarks and generalizations are made about SU2 x SU2 symmetry in Hubbard models. In particular, it is shown that the symmetry is a very general property of many Hubbard models. Periodicity is not a requirement for the validity of the symmetry. By a transformation of the creation and annihilation operators into anticommuting gamma matrices, the symmetry is made transparent.
