Codimension-two prime ideals of the Witt enveloping algebra

Let $W$ be the Witt algebra, let $\operatorname{U}(W)$ be its universal enveloping algebra, and let $\pi_\gamma$ be the family of representations defined in the paper, with kernels $\operatorname{Ker}\pi_\gamma$. The Witt codimension-two prime-ideal conjecture. The ideals $\operatorname{Ker}\pi_\gamma$ comprise all prime ideals of $\operatorname{U}(W)$ of co-Gelfand--Kirillov dimension $2$. The paper constructs these ideals and relates them to dimension-two pseudo-orbits, but the asserted classification remains unresolved in the supplied text.
