Geometry Questions

Overview

This hypergraph has MathOverflow users as nodes and question-category co-answer groups as hyperedges. The categories are derived from tags involving geometry. The dataset was derived from the Stack Exchange data dump.

Attributes

• category : string: The category of the question that the users co-answered, derived from the question tags.

Simplicial Interpretation

For simplicial complexes, the suggested construction to satisfy simplicial closure is to interpret the category label as a set. Non-maximal simplices get the category of all maximal simplices they are contained in.
