摘要

We prove that for many pairs H1,H2H_1, H_2 of root subgroups of the automorphism group Aut(C2)\text{Aut}(\mathbb{C}^2) the diagonal action of the group generated by H1,H2H_1, H_2 on (C2)m(\mathbb{C}^2)^m has an open orbit for any positive integer mm. The result is based on the study of the Lie algebra of polynomials in two variables with the standard Poisson bracket.
