Coends and the tensor product of $C$ -modules

Marco A. Pérez

We give an introduction to the concept of Kan extensions, and study its relation with the notions of coend and adjoint functors. We state and prove in detail a well known formula t…

Adjointness properties for relative extensions of disk and sphere chain complexes

Marco Pérez

We study the subgroup $E x t_{C}^{i} (F; C, D)$ of $E x t_{C}^{i} (C, D)$ formed by those $i$ -extensions of $C$ by $D$ in an Abelian category…

Degreewise n-projective and n-flat model structures on chain complexes

Marco Pérez

In the paper "Cotorsion Pairs in C(R-Mod)", the authors construct an abelian model structure on the category of chain complexes Ch(R), where the class of cofibrant objects is given…
