Zbigniew Jelonek SOLVING POLYNOMIAL EQUATIONS

law Janeczko and Zbigniew Jelonek

Let K be the field of real or complex numbers. Let (X ∼= K, ω) be a symplectic affine space. We study the group of polynomial symplectomorphisms of X. We show that for an arbitrary k ∈ N the group of polynomial symplectomorphisms acts k-transitively on X. Moreover, if 2 l 2n− 2 then elements of this group can be characterized by polynomial automorphisms which preserve the symplectic type of all...
