Abstract: | Infinitesimal conformal transformations of Rn are always polynomialand finitely generated when n > 2. Here we prove that theLie algebra of infinitesimal conformal polynomial transformationsover Rn, n 2, is maximal in the Lie algebra of polynomial vectorfields. When n is greater than 2 and p, q are such that p +q = n, this implies the maximality of an embedding of so(p +1, q + 1, R) into polynomial vector fields that was revisitedin recent works about equivariant quantizations. It also refinesa similar but weaker theorem by V. I. Ogievetsky. 1991 MathematicsSubject Classification 17B66, 53A30. |
