On invariants of representations of Weyl groups associated with the cohomology of toric varieties

Tao Gong

For a Weyl group $W$ and a $W$ -permutohedron $P$ , there are associated toric varieties $X_{P}$ and $X_{P / W_{K}}$ for any parabolic subgroup $W_{K}$ of $W$ , since the quotient $P / W_{K}$ can…

Toric varieties modulo reflections

Colin Crowley, Tao Gong, Connor Simpson

Let $W$ be a finite group generated by reflections of a lattice $M$ . If a lattice polytope $P \subset M \otimes_{Z} R$ is preserved by $W$ , then we show that the quo…

Homotopy Types Of Toric Orbifolds From Weyl Polytopes

Tao Gong

Given a reduced crystallographic root system with a fixed simple system, it is associated to a Weyl group $W$ , parabolic subgroups $W_{K}$ 's and a polytope $P$ which is the convex hu…
