Abstract
We provide new equivalent conditions for an algebra to be -finite, analogous to those established by L. Demonet, O. Iyama, and G. Jasso, but within the category of projective presentations . We show that an algebra has finitely many isomorphism classes of basic -term silting objects if and only if all cotorsion pairs in are complete. Furthermore, we establish that this criterion is also equivalent to all thick subcategories in having enough injective and projective objects.
