Coderived and contraderived categories for a cotorsion pair, flat-type cotorsion pairs, and relative periodicity

Leonid Positselski

Given a hereditary complete cotorsion pair $(A, B)$ generated by a set of objects in a Grothendieck category $K$ , we construct a natural equivalence between…

Compact generators of the contraderived category of contramodules

Leonid Positselski, Jan Stovicek

We consider the contraderived category of left contramodules over a right linear topological ring $R$ with a countable base of neighborhoods of zero. Equivalently, this i…

Semialgebras associated with nonunital algebras and $k$ -linear subcategories

Leonid Positselski

This paper is a sequel to arXiv:2307.13358 and arXiv:2308.16090. A construction associating a semialgebra with an algebra, subalgebra, and a coalgebra dual to the subalgebra played…
