The WittVectors package for Macaulay2

Anne Fayolle, Abhay Goel, Devlin Mallory +2

We implement a Macaulay2 package for computations involving rings of truncated Witt vectors $W_{n} (R)$ of a finitely generated $\F_p$-algebra $R$ . This package includes ring operatio…

Quasi- $F^{\infty}$ -split height versus quasi- $F$ -regular height for rational double points and graded rings

Teppei Takamatsu, Shou Yoshikawa

In this paper, we study a phenomenon concerning quasi- $F$ -singularities: under suitable hypotheses, the finiteness of the quasi- $F^{\infty}$ -split height ( $ht^{\infty}$ ) i…
