Bertini's theorem for $F$ -rational $F$ -pure singularities

Alessandro De Stefani, Thomas Polstra, Austyn Simpson

Let $k$ be an algebraically closed field of characteristic $p > 0$ , and let $X \subseteq P_{k}^{n}$ be a quasi-projective variety that is $F$ -rational and $F$ -pure. We prove that…

Differential and symbolic powers of ideals

Alessandro De Stefani, Eloísa Grifo, Jack Jeffries

We characterize symbolic powers of prime ideals in polynomial rings over any field in terms of $Z$ -linear differential operators, and of prime ideals in polynomial rings o…
