We give a geometric realization, the tagged rotation, of the AR-translation on the generalized cluster category associated to a surface $$\mathbf {S}$$S with marked points and non-empty boundary, which generalizes Brüstle–Zhang’s result for the puncture free case. As an application, we show that the intersection of the shifts in the 3-Calabi–Yau derived category $$\mathrm{\mathcal {D} }(\Gamma _{\mathbf {S}})$$D(ΓS) associated to the surface and the corresponding Seidel–Thomas braid group of…

It is proved that the oriented flip graph is a polygonal, congruence-uniform lattice, which generalizes the classical lattice of noncrossing set partitions and inherits a cyclic action from its congruent lattice structure.
