This is a “laboratory” of work in various stages.
- An explanation of the inductive construction of the canonical basis.
- Rexgraph: looking at the reduced expression graph for elements in small groups.
- Bruhat order: looking at the Bruhat order in groups, and quotients by parabolic subgroups.
- Root poset: shows the additive root poset, and the root graph made by reflections.
- LS Paths: displaying Lakshmibai-Seshadri paths.
- Stability Conditions: stability conditions of root systems.
- Notes: The digital equivalent of scribbles on a bit of paper.
