Projects

Lean HoG

Lean HoG makes more than 23,000 graphs from the House of Graphs available inside the Lean proof assistant, together with formally verified proofs of selected properties.

MathBases

A catalogue of more than 130 mathematical databases.

This project is the successor of the Catalogue of Mathematical Datasets.

MathDataHub

A semantic portal for mathematical datasets. This project is a successor of DiscreteZOO

Mathswitch

Infrastructure for relaying and exchanging mathematical concepts. Mathswitch gathers concepts from sources such as Wikipedia, Wikidata, nLab, MathWorld, and ProofWiki, and links them when they refer to the same idea. It currently aligns more than 40,000 concept entries across 7 sources.

Catalogue of Mathematical Datasets

An earlier project, succeeded by MathBases.

DiscreteZOO

DiscreteZOO is a repository of graphs and other discrete objects. Various censuses of graphs and other objects exist on the web. DiscreteZOO aims to give them a common home, make them easily accessible and searchable according to some precomputed properties. MathDataHub builds on the ideas from DiscreteZOO.

Code4math

code4math is a professional organization dedicated to the advancement of mathematical research through the development of high-quality sociotechnical infrastructure: software, databases, communities, and more. It was founded as an outcome of the American Institute of Mathematics’ 2023 December workshop on Open-source cyberinfrastructure supporting mathematics research. I am a member of its steering committee.
