Abstract: | Let Δn be a cyclic quiver of n vertices and let 𝒯n denote the category of nilpotent representations of Δn over a field. In the present paper, we study the stability conditions on 𝒯n and describe the semistable subcategories of 𝒯n with a fixed slope. This provides an alternative characterization of the thick subcategories of 𝒯n. Further, we obtain a relationship between the Harder–Narasimhan system for Δn and the Ringel–Hall algebra of Δn. |
