Bounded -laminations and their intersection coordinates
Tsukasa Ishibashi, Zhe Sun, Wataru Yuasa
We introduce rational bounded -laminations on a marked surface as a proposed topological model for the rational tropical points $\mathcal{A}_{Sp_4,…

Skein and cluster algebras with coefficients for unpunctured surfaces
Tsukasa Ishibashi, Shunsuke Kano, Wataru Yuasa
We propose a skein model for the quantum cluster algebras of surface type with coefficients. We introduce a skein algebra of a walled surface $(Σ…

Skein and cluster algebras of unpunctured surfaces for
Tsukasa Ishibashi, Wataru Yuasa
Continuing to our previous work [IY21](arXiv:2101.00643) on the -case, we introduce a skein algebra consisting of $\mathfrak…
