[PDF][PDF] The tropicalization of the moduli space of curves

D Abramovich, L Caporaso, S Payne - Ann. Sci. Éc. Norm. Supér.(4), 2015 - mat.uniroma3.it
We show that the skeleton of the Deligne-Mumford-Knudsen moduli stack of stable curves is
naturally identified with the moduli space of extended tropical curves, and that this is …

Tropical curves, graph complexes, and top weight cohomology of ℳ_ {ℊ}

M Chan, S Galatius, S Payne - Journal of the American Mathematical …, 2021 - ams.org
We study the topology of a space $\Delta _ {g} $ parametrizing stable tropical curves of
genus $ g $ with volume $1 $, showing that its reduced rational homology is canonically …

A moduli stack of tropical curves

R Cavalieri, M Chan, M Ulirsch, J Wise - Forum of Mathematics …, 2020 - cambridge.org
We contribute to the foundations of tropical geometry with a view toward formulating tropical
moduli problems, and with the moduli space of curves as our main example. We propose a …

Logarithmic double ramification cycles

D Holmes, S Molcho, R Pandharipande… - arXiv preprint arXiv …, 2022 - arxiv.org
Let $ A=(a_1,\ldots, a_n) $ be a vector of integers which sum to $ k (2g-2+ n) $. The double
ramification cycle $\mathsf {DR} _ {g, A}\in\mathsf {CH}^ g (\mathcal {M} _ {g, n}) $ on the …

Topology of moduli spaces of tropical curves with marked points

M Chan, S Galatius, S Payne - Facets of algebraic geometry, 2022 - books.google.com
This article is a sequel to [14]. We study a space g, n of genus g stable, n-marked tropical
curves with total edge length 1. Its rational homology is identified with both top-weight …

Tropicalizing the space of admissible covers

R Cavalieri, H Markwig, D Ranganathan - Mathematische Annalen, 2016 - Springer
We study the relationship between tropical and classical Hurwitz moduli spaces. Following
recent work of Abramovich, Caporaso and Payne, we outline a tropicalization for the moduli …

Degeneration of linear series from the tropical point of view and applications

M Baker, D Jensen - Nonarchimedean and tropical geometry, 2016 - Springer
We discuss linear series on tropical curves and their relation to classical algebraic geometry,
describe the main techniques of the subject, and survey some of the recent major …

Algebraic and tropical curves: comparing their moduli spaces

L Caporaso - arXiv preprint arXiv:1101.4821, 2011 - arxiv.org
We construct the moduli space for equivalence classes of n-pointed tropical curves of genus
g, together with its compactification given by weighted tropical curves, and establish some of …

Tropical hyperelliptic curves

M Chan - Journal of Algebraic Combinatorics, 2013 - Springer
We study the locus of tropical hyperelliptic curves inside the moduli space of tropical curves
of genus g. We define a harmonic morphism of metric graphs and prove that a metric graph …

Top weight cohomology of moduli spaces of Riemann surfaces and handlebodies

L Hainaut, D Petersen - arXiv preprint arXiv:2305.03046, 2023 - arxiv.org
We show that a certain locus inside the moduli space $ M_g $ of hyperbolic surfaces, given
by surfaces with" sufficiently many" short geodesics, is a classifying space of the handlebody …
