Wide subcategories are semistable

アブストラクト

This talk is based on arXiv:1705.07636.

For an arbitrary finite dimensional algebra Λ, we prove that any wide subcategory of modΛ satisfying a certain finiteness condition is θ-semistable for some stability condition θ.

More generally, we show that wide subcategories of modΛ associated with two-term presilting complexes of Λ are semistable.

This provides a complement for Ingalls-Thomas-type bijections for finite dimensional algebras.
