The TestIdeals package for Macaulay2
Alberto F. Boix, Daniel J. Hernández, Zhibek Kadyrsizova +7
This note describes a \emph{Macaulay2} package for computations in prime characteristic commutative algebra. This includes Frobenius powers and roots, -linear and -l…
Frobenius powers of some monomial ideals
Daniel J. Hernández, Pedro Teixeira, Emily E. Witt
In this paper, we characterize the (generalized) Frobenius powers and critical exponents of two classes of monomial ideals of a polynomial ring in positive characteristic: powers o…
Frobenius powers
Daniel J. Hernández, Pedro Teixeira, Emily E. Witt
This article extends the notion of a Frobenius power of an ideal in prime characteristic to allow arbitrary nonnegative real exponents. These generalized Frobenius powers are close…
Local m-adic constancy of F-pure thresholds and test ideals
Daniel J. Hernández, Luis Núñez-Betancourt, Emily E. Witt
In this note, we consider a corollary of the ACC conjecture for F-pure thresholds. Specifically, we show that the F-pure threshold (and more generally, the test ideals) associated…
