Skein and cluster algebras of unpunctured surfaces for ${\mathfrak{sp}}_4$

Tsukasa Ishibashi, Wataru Yuasa

Continuing to our previous work [IY21](arXiv:2101.00643) on the ${\mathfrak{sl}}_3$-case, we introduce a skein algebra ${\mathcal{S}}_{{\mathfrak{sp}}_4,\Sigma }^q$ consisting of $\mathfrak{…
