Abstract: We study the representation theory of the Bershadsky-Polyakov algebra . In particular, Zhu algebra of is isomorphic to a certain quotient of the Smith algebra, after changing the Virasoro vector. We classify all modules in the category for the Bershadsky-Polyakov algebra for . In the case we show that the Zhu algebra has –dimensional indecomposable modules.
