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 $X \to X$ , giving ex…

Birational Invariance in Punctured Log Gromov-Witten Theory

Samuel Johnston

Given a log smooth scheme $(X, D)$ , and a log étale modification $(X ~, D ~) \to (X, D)$ , we relate the punctured Gromov-Witten theory of $(X ~, D ~)$ t…

A degree bound for strongly nilpotent polynomial automorphisms

Samuel G. G. Johnston

Let $k$ be a field of characteristic zero. Let $F = X + H$ be a polynomial mapping from $k^{n} \to k^{n}$ , where $X$ is the identity mapping and $H$ has only degree two terms and highe…
