If our space is like $\R \times \R_-$, one factor of space is cutting off some factor, but leaving some other factors intact. How does the fiber look like? It would be just the stop-fiber from the relevant factor, times the entire space from the non-partipating factor. So to show the Weinstein-ness, one just need to show that the two factors are. Now, where is the participating factor?… text/html 2026-03-15T20:40:33+00:00 pzhou (pzhou@undisclosed.example.com) https://pzhou.org/?image=notes%3Alaumon_nilpotent_cone.pdf&ns=notes&rev=1773607233&tab_details=history&mediado=diff&do=media text/html 2026-03-06T18:21:36+00:00 pzhou (pzhou@undisclosed.example.com) https://pzhou.org/?image=projects%3Aclusterhms%3Apasted%3A20260306-182136.png&ns=projects%3Aclusterhms%3Apasted&rev=1772821296&tab_details=history&mediado=diff&do=media <img src="https://pzhou.org/_media/projects/clusterhms/pasted/20260306-182136.png?w=500&h=79&t=1772821296&amp;tok=00db3d" alt="projects:clusterhms:pasted:20260306-182136.png" /> text/html 2026-02-27T19:23:54+00:00 pzhou (pzhou@undisclosed.example.com) https://pzhou.org/?image=blog%3Apasted%3A20260227-192354.png&ns=blog%3Apasted&rev=1772220234&tab_details=history&mediado=diff&do=media <img src="https://pzhou.org/_media/blog/pasted/20260227-192354.png?w=500&h=144&t=1772220234&amp;tok=7ecccd" alt="blog:pasted:20260227-192354.png" />
