Abstract:

We introduce the class of deformed preprojective algebras of generalized Dynkin graphs $\mathbb {A}_n$ ($n \geq 1$), $\mathbb {D}_n$ ($n \geq 4$), $\mathbb {E}_6$, $\mathbb {E}_7$, $\mathbb {E}_8$ and $\mathbb {L}_n$ ($n \geq 1$) and prove that it coincides with the class of all basic connected finite-dimensional self-injective algebras for which the inverse Nakayama shift $\nu ^{-1} S$ of every non-projective simple module $S$ is isomorphic to its third syzygy $\Omega ^3 S$.
