Ulrich sheaves, the arithmetic writhe and algebraic isotopies of space curves
Daniele Agostini, Mario Kummer
We establish a connection between the theory of Ulrich sheaves and -homotopy theory. For instance, we prove that the -degree of a morphism between proje…
Some thoughts and experiments on Bergman's compact amalgamation problem
Michael Joswig, Mario Kummer, Andreas Thom +1
We study the question whether copies of in can be amalgamated in a compact group. This is the simplest instance of a fundamental open problem in the theory o…
Bounding the signed count of real bitangents to plane quartics
Mario Kummer, Stephen McKean
Using methods from enriched enumerative geometry, Larson and Vogt gave a signed count of the number of real bitangents to real smooth plane quartics. This signed count depends on a…
A signed count of 2-torsion points on real abelian varieties
Mario Kummer
We prove that a natural signed count of the -torsion points on a real principally polarized abelian variety always equals to where is the dimension of . When…
