In Preparation

The information below is preliminary and cannot be trusted! (v)

Sweeping clean a tree and ${\mathcal {A}}(\Gamma )\equiv {\mathcal {A}}(\uparrow _{b_{1}(\Gamma )})$ .

${\mathcal {A}}(\uparrow _{n})$ is a VS-algebra (see more at VS, TS and TG Algebras).
In the coordinates above, write the $TR\Phi B$ $TR\Phi B$ relations in various algebraic notations.
- R4: $(1230)^{\star }B^{\pm }\cdot (1213)^{\star }B^{\pm }\cdot (1023)^{\star }\Phi =(1123)^{\star }\Phi \cdot (1233)^{\star }B^{\pm }$ or $(B_{1a}^{\pm }B_{2a}^{\pm }\Phi _{1a};B_{1b}^{\pm }B_{2b}^{\pm };B_{1c}^{\pm }B_{2b}^{\pm }\Phi _{1b};B_{2c}^{\pm }\Phi _{1c})=(\Phi _{2a}B_{3a}^{\pm };\Phi _{2a}B_{3b}^{\pm };\Phi _{2b}B_{3c}^{\pm };\Phi _{2c}B_{3c}^{\pm })$ .
- $B^{\pm }$ in terms of $\Phi$ and $R$ and $R$ in terms of $T$ .
- R3, R2, R1
- Symmetry of $\Phi$ and of $B^{\pm }$ .
- $u$ , $d$ and $\#$
- Idempotence for $T$ , $R$ , $\Phi$ and $B^{\pm }$ .
