We consider the algebras \(e_i \Pi^\lambda(Q) e_i\), where \(\Pi^\lambda(Q)\) is the deformed preprojective algebra of weight \(\lambda\) and \(i\) is some vertex of \(Q\), in the case where \(Q\) is an extended Dynkin diagram and \(\lambda\) lies on the hyperplane orthogonal to the minimal positive...
