Deformed preprojective algebras of generalized Dynkin type Ln: Classification and symmetricity

We give a complete classification of the isomorphism classes of the deformed preprojective algebras of generalized Dynkin type Ln and show that all these algebras are symmetric. Moreover, we show that the deformed preprojective algebras of type Ln are isomorphic to the stable Auslander algebras of simple plane curve singularities of Dynkin type A2n.
