Vector bundles on Olsson fans
Luca Battistella, Francesca Carocci, Jonathan Wise
Artin fans are algebro-geometric incarnations of cone complexes. We study weakly convex Olsson fans, generalising Artin fans in two ways: first, they admit lineality spaces, thus i…
Residues and Gorenstein Contractions of Genus One Curves
Adrian Neff, Jonathan Wise
Let be a genus one nodal curve over a local artinian base and let be a proper subcurve of genus one. We define residues for curves over local artinian rings, then define ge…
Tropical pseudostable curves
Renzo Cavalieri, Steffen Marcus, Jonathan Wise
We study the tropical version of the contraction morphism between moduli spaces of stable and pseudostable curves. By promoting to a logarithmic morphis…
Images of abelian schemes
Jeff Achter, Sebastian Casalaina-Martin, Jonathan Wise
We provide some conditions for the image of a morphism of abelian schemes to again be an abelian scheme. For context, in characteristic 0, the image is always an abelian scheme; in…
Remarks on logarithmic étale sheafification
Samouil Molcho, Jonathan Wise
We prove criteria for a presheaf on logarithmic schemes to be a sheaf in the full logarithmic étale topology and describe several situations where the structure sheaf and logarithm…
Pseudostable Hodge integrals
Renzo Cavalieri, Joel Gallegos, Dustin Ross +2
This paper initiates a study of Hodge integrals on moduli spaces of pseudostable curves. We prove an explicit comparison formula that allows one to effectively compute any pseudost…
