摘要: Let $A$ be a connected Nakayama algebra of infinite global dimension. We investigate the singularity category of $A$ and the duality between the singularity category of $A$ and its opposite algebra. We prove that the resolution quivers of $A$ and its opposite algebra have the same number of cycles and the same number of cyclic vertices.
