Continuing to our previous work [IY21] on the sl3-case, we introduce a skein algebra S q sp 4 ,Σ consisting of sp4-webs on a marked surface Σ with certain “clasped” skein relations at special points, and investigate its cluster nature. We also introduce a natural Zq-form S Zq sp 4 ,Σ ⊂ S q sp 4 ,Σ, while the natural coefficient ring R of S q sp 4 ,Σ includes the inverse of the quantum integer [2]q. We prove that its boundary-localization S Zq sp 4 ,Σ[∂ ] is included into a quantum cluster…

For a symmetrizable Kac-Moody Lie algebra $\mathfrak{g}$, we construct a family of weighted quivers $Q_m(\mathfrak{g})$ ($m \geq 2$) whose cluster modular group $\Gamma_{Q_m(\mathfrak{g})}$ contains

By introducing a finer version of the Kauffman bracket skein algebra, we show how to decompose the Kauffman bracket skein algebra of a surface into elementary blocks corresponding to the triangles in

We continue the study of cluster algebras initiated in math.RT/0104151 and math.RA/0208229. We develop a new approach based on the notion of an upper cluster algebra, defined as an intersection of

We derive an inductive, combinatorial definition of a polynomial-valued regular isotopy invariant of links and tangled graphs. We show that the invariant equals the Reshetikhin-Turaev invariant
