Cohomological dimension, Lyubeznik numbers, and connectedness properties in mixed characteristic
Daniel J. Hernández, Luis Núñez-Betancourt, Felipe Pérez +1
We establish a "second vanishing theorem" for local cohomology modules over regular rings of unramified mixed characteristic, which relates the connectedness of the spectrum of a r…
A survey on the Lyubeznik numbers
Luis Núñez-Betancourt, Emily E. Witt, Wenliang Zhang
The Lyubeznik numbers are invariants of a local ring containing a field that capture ring-theoretic properties, but also have numerous connections to geometry and topology. We disc…
F-pure thresholds of homogeneous polynomials
Daniel J. Hernández, Luis Núñez-Betancourt, Emily E. Witt +1
In this article, we investigate F-pure thresholds of polynomials that are homogeneous under some N-grading, and have an isolated singularity at the origin. We characterize these in…
