Punctured log Gromov-Witten theory of log modifications and double ramification cycles with target log variety

Samuel Johnston

We expand upon a previous study conducted by the author on the behavior of punctured log Gromov-Witten theory under log étale modifications , giving ex…

A fast Berry-Esseen theorem under minimal density assumptions

Samuel G. G. Johnston

Let be i.i.d.\ random variables distributed like . Suppose that the first moments of agree with that of t…

Universality classes for the coalescent structure of heavy-tailed Galton-Watson trees

Simon C. Harris, Samuel G. G. Johnston, Juan Carlos Pardo

Consider a population evolving as a critical continuous-time Galton-Watson (GW) tree. Conditional on the population surviving until a large time , sample individuals uniform…

Random planar trees and the Jacobian conjecture

Elia Bisi, Piotr Dyszewski, Nina Gantert +3

We develop a probabilistic approach to the celebrated Jacobian conjecture, which states that any Keller map (i.e. any polynomial mapping who…

Birational Invariance in Punctured Log Gromov-Witten Theory

Samuel Johnston

Given a log smooth scheme , and a log étale modification , we relate the punctured Gromov-Witten theory of t…

Beads on the torus via scaling limits of dimer matchings

Samuel G. G. Johnston

In a previous article, we develop a continuous version of Kasteleyn theory to study the bead model on the torus. These are the point processes on the semi-discrete torus $\mathbb{T…
