Archaeological Seminar with Dr. Colin Connors (guest researcher from University of Washington).

A numerical semigroup is said to be Weierstrass if it is the semigroup of pole orders of rational functions that are regular at all but one point of some compact Riemann surface or smooth algebraic curve. Hurwitz asked in 1892 whether all numerical semigroups can occur. Buchweitz in 1980 gave the first examples of Non-Weierstrass semigroups. In this paper we give a new method, using syzygies, to show that certain semigroups are not Weierstrass, including the first one of multiplicity 6 (the lowest possible) and genus 13 (the lowest known). We give many other examples to which the method applies.

Herman Martens Meyer is a PhD candidate in the Department of Mathematics at the University of Oslo. Prior to starting his PhD, he completed an integrated Master’s degree in Applied Physics and Mathematics at the Norwegian University of Science and Technology (NTNU). For his Master’s thesis, he worked on identifying subsurface turbulence using light reflected from a free surface. His research interests include wave turbulence, breaking waves, and free-surface turbulence.

Around 1970, Gruson and Raynaud proved that one may render a morphism of finite presentation flat by blowing up an ideal in the target, with rather mild restrictions on the involved schemes. New proofs, entirely different from the one of Gruson and Raynaud, have been found by Fujiwara and Kato and by Guignard. The two proofs are basically the same, both using Temkin's relative Zariski–Riemann spaces, the limits of all interesting blow-ups. These spaces are quasi compact locally ringed spaces whose local rings are close to being valuation rings, so that almost anything is flat, and due to their quasi compactness, one may descend flatness to a genuine blow-up.

Notes for the talk here.
