The Briançon-Skoda theorem for pseudo-rational and Du Bois singularities and uniformity in excellent rings

Linquan Ma, Peter M. McDonald, Rebecca R. G. +1

Suppose $J = (f_{1}, \dots, f_{n})$ is an $n$ -generated ideal in any ring $R$ . We prove a general Briançon-Skoda-type containment relating the integral closure $J^{n + k - 1}$ w…

Lech-Mumford constant and stability of local rings

Linquan Ma, Ilya Smirnov

We study further Mumford's notion of local semistability and, in particular, show that semistable singularities are log canonical under mild assumptions. We provide many new exampl…

On complete integral closedness of the $p$ -adic completion of absolute integral closure

Raymond Heitmann, Linquan Ma

Fix a prime $p$ and let $(R, m)$ be a Noetherian complete local domain of mixed characteristic $(0, p)$ with fraction field $K$ . Let $R^{+}$ denote the absolute integral clo…
