Kleinian singularities and algebras generated by elements that have given spectra and satisfy a scalar sum relation
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...
