Flat commutative ring epimorphisms of almost Krull dimension zero

Leonid Positselski

We consider flat epimorphisms of commutative rings $R \to U$ such that, for every ideal $I \subset R$ for which $I U = U$ , the quotient ring $R / I$ is semilocal of Krull dimension zero.…

Remarks on derived complete modules and complexes

Leonid Positselski

Let $R$ be a commutative ring and $I \subset R$ a finitely generated ideal. We discuss two definitions of derived $I$ -adically complete (also derived $I$ -torsion) complexes of $R$ -m…
