This reduces the proof of first two items of Theorem 1.2 to just proving that any automorphism on either a conic bundle over P 1 or a rational del Pezzo surface induces an

For any g, the Cremona transformations with 4, 2 or 0 real base points generate the (non-orientable) mapping class group M g.. Finally, we can put these results together to obtain

In Corollary 4.3, we verify that the centralizer in a generalized reductive group G§ of an elementary abelian subgroup A c: Gg(W) of order prime to p is again a generalized

(The above N = R ® 1^ is the only factor of Araki-Woods of type 11^, we take the notation Ro^ for it, as in [1].) We shall in another paper discuss the implications of this fact on

As the number of isomorphism classes of such curves is infinite, we obtain infinitely many conjugacy classes of de Jonquières involutions in the Cremona group.. (In fact, there

In fact the admissible diagrams for Weyl groups of type A are graphs, all of whose connected components are Dynkin diagrams of type A.. These admissible diagrams
