Abstract

We construct classes of Z2×Z2Z_2 \times Z_2-graded Lie algebras corresponding to the classical Lie algebras, in terms of their defining matrices. For the Z2×Z2Z_2 \times Z_2-graded Lie algebra of type AA, the construction coincides with the previously known class. For the Z2×Z2Z_2 \times Z_2-graded Lie algebra of type BB, CC and DD our construction is new and gives rise to interesting defining matrices closely related to the classical ones but undoubtedly different. We also give some examples and possible applications to parastatistics.
