Alpöge's counterexample to the JC, Economic Stabilization, and Zhao's Vanishing Conjecture
Abstract
In this paper, we apply stabilization techniques which are economic in the number of added dimensions to a slightly tweaked version of Alpöge's counterexample to JC(3) and JC(3,7). The first idea which lead to more economic stabilization is to bypass the degree 3 reduction of Bass, Connell and Wright in the construction of a counterexample to HJC(n). We construct counterexamples to HJC(15), VC(28), and HVC(30). On the other hand, we will perform degree 3 reduction after all to obtain counterexamples of low degree. We construct counterexamples to JC(12,3), HJC(18,3), VC(34,4), and HVC(36,4). As an encore, we construct a cubic-linear counterexample to the Jacobian Conjecture in dimension 90. All presented counterexamples to the Jacobian Conjecture (Vanishing Conjecture) are over the (Gaussian) integers.
