Contraderived categories of CDG-modules
Leonid Positselski, Jan Stovicek
For any CDG-ring , we show that the homotopy category of graded-projective (left) CDG-modules over is equivalent to the quotient category of the ho…

Linear Reedy categories, quasi-hereditary algebras and model structures
Georgios Dalezios, Jan Stovicek
We study linear versions of Reedy categories in relation with finite dimensional algebras and abelian model structures. We prove that, for a linear Reedy category ove…

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 with a countable base of neighborhoods of zero. Equivalently, this i…
