الوصف: | For any non-zero complex number $q$, excluding finitely many roots of unity of small order, a linear basis for the $\mathrm{SL}(n)$ skein algebra of the twice punctured sphere is constructed. In particular, the skein algebra is a commutative polynomial algebra in $n-1$ generators, where each generator is represented by an explicit $\mathrm{SL}(n)$ web, without crossings, on the surface. This includes the case $q=1$, where the skein algebra is identified with the coordinate ring of the $\mathrm{SL}(n)$ character variety of the twice punctured sphere. The proof of both the spanning and linear independence properties of the basis depends on the so-called $\mathrm{SL}(n)$ quantum trace map, due originally to Bonahon-Wong in the case $n=2$. A consequence of the proof is that the polynomial algebra sits as a distinguished subalgebra of the L\^{e}-Sikora $\mathrm{SL}(n)$ stated skein algebra of the annulus. We end by discussing the relationship with Fock-Goncharov duality. Comment: 41 pages, 19 figures |
