Abstract
If and are co--structures of a triangulated category, then is called intermediate if . Our main results show that intermediate co--structures are in bijection with two-term silting subcategories, and also with support -tilting subcategories under some assumptions. We also show that support -tilting subcategories are in bijection with certain finitely generated torsion classes. These results generalise work by Adachi, Iyama, and Reiten.
