The generalized VOA leads to more general notions of locality, skew-symmetry, associativity, and commutivity than those for a VOSA as follows [1].
Before elaborating on sequential versus simultaneous we need to clarify on commutivity of constraints used in MrE approach.
However, because [X.sub.[GAMMA]] is not a graph, it is not guaranteed that [A.sup.n-2.sub.1] ([T.sub.n], [T.sub.0]) is free and we show that there are in fact commutivity relations between the generators of [A.sup.n-2.sub.1] ([T.sub.n], [T.sub.0]).
