Bounds on the plus-pure thresholds of some hypersurfaces in (ramified) regular rings

Marta Benozzo, Vignesh Jagathese, Vaibhav Pandey +3

We study the plus-pure threshold (ppt) of hypersurfaces in mixed characteristic. We show that the ppt limits to the $F$-pure threshold (fpt) as we ramify the base DVR. Additionally…
