... that D is a locally algebraic derivation. By Theorem 2, D = Ry+Dd, where Rv is the right multiplication by y = 2ZT ayuy, lor some y and d. Suppose that some nonzero 7 is y-admissible. We may simply order G in such a way that this 7>0. Call u( the leading term in an element 2 of L(G, g, f) if e is th ...
