Regularity and $K_{0}$ -Regularity under Finiteness Conditions

Rafael Parra

The purpose of this work is to investigate various notions of regularity from the perspective of finiteness conditions, with the ultimate goal of identifying broad classes of rings…

K-theory of n-coherent rings

Eugenia Ellis, Rafael Parra

Let $R$ be a strong $n$ -coherent ring such that each finitely $n$ -presented $R$ -module has finite projective dimension. We consider $F P_{n} (R)$ the full subcategory of $R…

Envelopes of commutative rings

Rafael Parra, Manuel Saorin

Given a significative class $F$ of commutative rings, we study the precise conditions under which a commutative ring $R$ has an $F$ -envelope. A full answer is obtained when $F$ is…
