Abstract

We give a geometric realization, the tagged rotation, of the AR-translation on the generalized cluster category associated to a surface S\mathbf{S} with marked points and non-empty boundary, which generalizes Br\"{u}stle-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 D(ΓS)\mathcal{D}(\Gamma_{\mathbf{S}}) associated to the surface and the corresponding Seidel-Thomas braid group of D(ΓS)\mathcal{D}(\Gamma_{\mathbf{S}}) is empty, unless S\mathbf{S} is a polygon with at most one puncture (i.e. of type A or D).
