In this talk, we introduce a notion of regular sequences in $R$-linear triangulated categories, where $R$ is a graded-commutative ring. As an application of this definition, we show that the length of regular sequences provides lower … LOCATION:LCB 222 URL:http://math.utah.edu/caseminar/2026-spring/ END:VEVENT BEGIN:VEVENT UID:20260213T140000-vignesh-jagathese@math.utah.edu DTSTART;TZID=America/Denver:20260213T140000 DTEND;TZID=America/Denver:20260213T150000 DTSTAMP:20260914T190003Z SUMMARY:Quasi-F-Purity, F-Pure Thresholds, and Arithmetic Supersingularity DESCRIPTION:Speaker: Vignesh Jagathese\, UIC\n\nA weakening of Frobenius splitting, Quasi-F-Splittings have proven to be a vital invariant in the study of varieties in positive characteristic, with numerous applications to arithmetic and birational geometry. This weaker condition extends the application of Frobenius to study singularities of … LOCATION:LCB 222 URL:http://math.utah.edu/caseminar/2026-spring/ END:VEVENT BEGIN:VEVENT UID:20260220T140000-ben-baily@math.utah.edu DTSTART;TZID=America/Denver:20260220T140000 DTEND;TZID=America/Denver:20260220T150000 DTSTAMP:20260914T190003Z SUMMARY:Classifying extremal pairs in equal characteristic DESCRIPTION:Speaker: Ben Baily\, U. Michigan\n\nLet R be a polynomial ring, J ⊆ R an ideal, and P a maximal ideal containing J. We consider invariants of the pair (R, J) which measure the singularities of the embedding Spec(R/J) ⊆ Spec(R) at P: the log canonical threshold (lct) in characteristic zero and the F-pure threshold (fpt) in positive … LOCATION:LCB 222 URL:http://math.utah.edu/caseminar/2026-spring/ END:VEVENT BEGIN:VEVENT UID:20260403T140000-vasudevan-srinivas@math.utah.edu DTSTART;TZID=America/Denver:20260403T140000 DTEND;TZID=America/Denver:20260403T150000 DTSTAMP:20260914T190003Z SUMMARY:Some finiteness results for étale fundamental groups in positive characteristics DESCRIPTION:Speaker: Vasudevan Srinivas\, University at Buffalo (SUNY and TIFR)\n\nThis talk will discuss some results on etale fundamental groups of varieties over an algebraically closed field of characteristic p > 0, based on joint work with Hélène Esnault and other coauthors. One result, along with Mark Schusterman, is that the tame fundamental group is finitely presented for … LOCATION:LCB 222 URL:http://math.utah.edu/caseminar/2026-spring/ END:VEVENT BEGIN:VEVENT UID:20260410T140000-vaibhav-pandey@math.utah.edu DTSTART;TZID=America/Denver:20260410T140000 DTEND;TZID=America/Denver:20260410T150000 DTSTAMP:20260914T190003Z SUMMARY:When is an ideal monomializable? DESCRIPTION:Speaker: Vaibhav Pandey\, Purdue University\n\nWe give a characterization of ideals which are monomial under some system of coordinates. Our motivation is to understand when does a homogeneous ideal I, in a polynomial ring S over an infinite field, admit a monomializable Artinian reduction. That is, when does there exist a choice of general … LOCATION:LCB 222 URL:http://math.utah.edu/caseminar/2026-spring/ END:VEVENT BEGIN:VEVENT UID:20260417T140000-tba@math.utah.edu DTSTART;TZID=America/Denver:20260417T140000 DTEND;TZID=America/Denver:20260417T150000 DTSTAMP:20260914T190003Z SUMMARY:Title DESCRIPTION:Speaker: TBA\, Institution\n\nAbstract LOCATION:LCB 222 URL:http://math.utah.edu/caseminar/2026-spring/ END:VEVENT END:VCALENDAR
