报告摘要
For any marked surface with any tagged triangulation, we consider the corresponding finite-dimensional completed Jacobian algebra associated with a specific non-degenerate potential defined by Labardini-Fragoso. We show that the band modules arising from simple loops are invariant under the Auslander-Reiten translation. Moreover, the $E-$invariants of two compatible (tagged) simple curves are zero.
