Cartier modules on toric varieties

Jen-Chieh Hsiao, Karl Schwede, Wenliang Zhang

Assume that $X$ is an affine toric variety of characteristic $p > 0$ . Let $Δ$ be an effective toric $Q$ -divisor such that $K_{X} + Δ$ is $Q$ -Cartier with index not divisible by $p$ and…

Two interesting examples of $D$ -modules in characteristic $p > 0$

Mordechai Katzman, Gennady Lyubeznik, Wenliang Zhang

We provide two examples of $D$ -modules in prime characteristic $p$ which answer two open problems in \cite{Lyubeznik} in the negative.

An upper bound on the number of F-jumping coefficients of a principal ideal

Mordechai Katzman, Gennady Lyubeznik, Wenliang Zhang

We prove a result relating the Jacobian ideal and the generalized test ideal associated to a principal ideal in $R = k [x_{1}, ..., x_{n}]$ with $[k : k^{p}] < \infty$ or in $R = k [[x_{1}, ..., x_{n}]]$ …

A Property of the Frobenius Map of a Polynomial Ring

Gennady Lyubeznik, Wenliang Zhang, Yi Zhang

Let R be a ring of polynomials in a finite number of variables over a perfect field k of characteristic p>0 and let F:R\to R be the Frobenius map of R, i.e. F(r)=r^p. We explicitly…
