dc.contributor.author: Frengley, Samuel
dc.description: This code supports my PhD thesis 'Explicit moduli spaces for curves of genus 1 and 2'. In particular, it contains:
(1) code which computes the numerical invariants of the surfaces $Z_{N,r}$, $W_{N,r}$ and those birational to them,
(2) code for studying congruences of quadratic-twist type (in particular models and $j$-maps for the modular curves $X^+(H_1, H_2)$),
(3) models for the surfaces $Z_{N,r}$ and $W_{N,r}$ for $N = 12, 14$ and for $(N,r) = (15,2), (15,7)$ computed in my thesis (and some others),
(4) examples of genus $2$ Jacobians with $7$-torsion in their Tate--Shafarevich groups.
Please read the READMEs in the various folders for more information.
Concept Lab: Precomputed Associations for Shared Lexis Tool and Associated Files (Public)Recchia, GabrielJones, EwanNulty, Paulde Bolla, PeterRegan, Johnhttps://www.repository.cam.ac.uk/handle/1810/3360542023-05-04T01:48:35Zdc.title: Concept Lab: Precomputed Associations for Shared Lexis Tool and Associated Files (Public)
dc.contributor.author: Recchia, Gabriel; Jones, Ewan; Nulty, Paul; de Bolla, Peter; Regan, John
dc.description: This dataset consists of:
I. Source code and documentation for the "Shared Lexis Tool", a Windows desktop application that provides a means of exploring all of the words that are statistically associated with a word provided by the user, in a given corpus of text (for certain predefined corpora), over a given date range.
II. Source code and documentation for the "Coassociation Grapher", a Windows desktop application. Given a particular word of interest (a “focal token”) in a particular corpus of text, the Coassociation Grapher allows you to view the relative probability of observing other terms (“bound tokens”) before or after the focal token.
III. Numerous precomputed files that need to be hosted on a webserver in order for the Shared Lexis Tool to function properly;
IV. Files that were created in the course of conducting the research described in "Tracing shifting conceptual vocabularies through time" and "The idea of liberty" (full citations in above section 'SHARING/ACCESS INFORMATION'), including "cliques" (https://en.wikipedia.org/wiki/Clique_(graph_theory)) of words that frequently appear together;
V. Source code of text-processing scripts developed by the Concept Lab, primarily for the purpose of generating precomputed files described in section III, and associated data.
The Shared Lexis Tool and Coassociation Grapher (and the required precomputed files) are also being hosted at https://concept-lab.lib.cam.ac.uk/ from 2018 to 2023, and therefore those who are merely interested in using the tools within this time frame will have no use for the present dataset. However, these files may be useful for individuals who wish to host the files on their own webserver, for example, in order to use the Shared Lexis tool past 2023. See README.txt for more information.

dc.description: As described in my PhD thesis K-Theory of Fermat Curves I give PARI/GP scripts and programs written in C that numerically verify Beilinson's conjecture on certain quotients of Fermat curves.
