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

We consider the algebras eiΠλ
 (Q)ei
 , where Πλ
 (Q)
 is the deformed preprojective algebra of weight λ and i is some vertex of Q, in the case where Q is an extended Dynkin diagram and
 λ lies on the hyperplane orthogonal to the minimal positive imaginary roo...

 , where Πλ
 (Q)
 is the deformed preprojective algebra of weight λ and i is some vertex of Q, in the case where Q is an extended Dynkin diagram and
 λ lies on the hyperplane orthogonal to the minimal positive imaginary root δ. We prove that the center of eiΠλ

 is isomorphic
 to Oλ

 a standard identity of degree k holds in eiΠλ
