One is thus tempted to try to prove the Jacobian conjecture by “feeding” such group actions into the picture. For example, let . = ..(?) act

(The arithmetical rank is the least number of elements generating an ideal up to radical.) It turns out that there is a general upper bound only depending on the combinatorial data of the poset.
