A digestion of the Jacobian conjecture counterexample

โœจ Check out this trending post from Hacker News ๐Ÿ“– ๐Ÿ“‚ **Category**: ๐Ÿ’ก **What Youโ€™ll Learn**: The notorious Jacobian conjecture can be formulated concretely over the complex numbers as follows. Conjecture 1 (Jacobian Conjecture) Let be a polynomial map in complex variables, whose Jacobian is a non-zero constant. Then is invertible (with polynomial inverse). The condition that the Jacobian is non-zero is equivalent to being locally invertible.
