Pseudo-dualizing complexes and pseudo-derived categories

, 2020
The definition of a pseudo-dualizing complex is obtained from that of a dualizing complex by dropping the injective dimension condition, while retaining the finite generatedness and homothety isomorphism conditions.

Gluing approximable triangulated categories

Forum of Mathematics, Sigma, 2023
AbstractGiven a bounded-above cochain complex of modules over a ring, it is standard to replace it by a projective resolution, and it is classical that doing so can be very useful.Recently, a modified version of this was introduced in triangulated categories other than the derived category of a ring.

Balanced Pairs on Triangulated Categories

Algebra Colloquium, 2023
Let [Formula: see text] be a triangulated category. We first introduce the notion of balanced pairs in [Formula: see text], and then establish the bijective correspondence between balanced pairs and proper classes [Formula: see text] with enough [Formula: see text]-projectives and [Formula: see text]-injectives.

Presheaves of triangulated categories and reconstruction of schemes

, 2002
To any triangulated category with tensor product $(K,\otimes)$, we associate a topological space $Spc(K,\otimes)$, by means of thick subcategories of $K$, a la Hopkins-Neeman-Thomason. Moreover, to each open subset $U$ of $Spc(K,\otimes)$, we associate a
