Realizability of tropical canonical divisors

M Möller, M Ulirsch, A Werner - Journal of the European Mathematical …, 2020 - ems.press
We use recent results by Bainbridge–Chen–Gendron–Grushevsky–Möller on
compactifications of strata of abelian differentials to give a comprehensive solution to the …

[PDF][PDF] Tropicalization of the universal Jacobian

M Melo, S Molcho, M Ulirsch… - Épijournal de Géométrie …, 2022 - epiga.episciences.org
In this article we provide a stack-theoretic framework to study the universal tropical Jacobian
over the moduli space of tropical curves. We develop two approaches to the process of …

Principal bundles on metric graphs: The GLn case

A Gross, M Ulirsch, D Zakharov - Advances in Mathematics, 2022 - Elsevier
Using the notion of a root datum of a reductive group G we propose a tropical analogue of a
principal G-bundle on a metric graph. We focus on the case G= GL n, ie the case of vector …

Logarithmic Donaldson–Thomas theory

D Maulik, D Ranganathan - Forum of Mathematics, Pi, 2024 - cambridge.org
Let X be a smooth and projective threefold with a simple normal crossings divisor D. We
construct the Donaldson–Thomas theory of the pair enumerating ideal sheaves on X relative …

Kirchhoff's theorem for Prym varieties

Y Len, D Zakharov - Forum of Mathematics, Sigma, 2022 - cambridge.org
We prove an analogue of Kirchhoff's matrix tree theorem for computing the volume of the
tropical Prym variety for double covers of metric graphs. We interpret the formula in terms of …

A non-Archimedean analogue of Teichmüller space and its tropicalization

M Ulirsch - Selecta Mathematica, 2021 - Springer
In this article we use techniques from tropical and logarithmic geometry to construct a non-
Archimedean analogue of Teichmüller space T¯ g whose points are pairs consisting of a …

Realizability of tropical pluri‐canonical divisors

F Röhrle, J Schwab - Journal of the London Mathematical …, 2024 - Wiley Online Library
Consider a pair consisting of an abstract tropical curve and an effective divisor from the
linear system associated to kk times the canonical divisor for k∈ Z⩾ 1 k∈Z_\geqslant1. In …

[图书][B] Tropical Geometry of Curves

MV Brandt - 2020 - search.proquest.com
Algebraic geometry is a classical subject which studies shapes arising as zero sets of
polynomial equations. Such objects, called varieties, may be quite complicated but many …

Divisorial motivic zeta functions for marked stable curves

M Brandt, M Ulirsch - Michigan Mathematical Journal, 2022 - projecteuclid.org
We define a divisorial motivic zeta function for stable curves with marked points, which
agrees with Kapranov's motivic zeta function when the curve is smooth and unmarked. We …
