# Malthe Sporring

I am a PhD student of Clark Barwick at the University of Edinburgh. I am interested in homotopy theory and (higher) category theory. I am also interested in theorem proving via LEAN and automated assessment via STACK. When I’m not thinking about mathematics, I may be swing dancing or bouldering.

# Notes

Informal notes on various topics. Comments and corrections are welcomed. ### Persistent homology

(December 2022) Notes on persistent homology, as part of a GlaMS (Glasgow-Maxwell school) group project. Joint with Yan Yau Cheng and Adrián Doña Mateo.

### Axiomatic homology theory

(September 2021) Undergraduate notes on axiomatic homology theory. Homology is typically introduced as singular homology, with theorems proven explicitly using chain calculations. We take a different approach, defining a homology theory axiomatically as by Eilenberg and Steenrod, and then proving classical theorems directly from the axioms. This project was supervised by Prof. Clark Barwick and funded by the University of Edinburgh School of Mathematics Vacation Scholarship and College Vacation Scholarship funds.

# STACK

STACK is an open source online assessment system for STEM subjects. I have been involved in STACK since 2019 - here are some of my contributions:- Designing the STACK website stack-assessment.org.
- Editing a collection of case studies.
- Developing a video tutorial series.
- Designing STACK quizzes for The University of Edinburgh, Heriot-Watt University and The University of Glasgow.
