By definition, G0 is the subalgebra generated by all words ei1 ei2 . But for any v ∈ V , ei1 ei2 v = −ei1 vei2 = vei1 ei2 ; Basic Results 31 thus, ei1 ei2 ∈ Cent(G). The same argument also shows that if a, b ∈ G are homogeneous, then ab = ±ba, the − sign occurring iff both a, b are odd. In particular, Cent(G) = G0 . G can also be described in the following way: We say two elements a, b of an algebra A strictly anticommute if arb = −bra for all r ∈ A. 29. (i) Any two odd elements a, b of G strictly anticommute.
