simplicial is a Python library for experimenting with simplicial topological complexes.
Simplicial topology is used to build topological spaces from smaller discrete units called simplices (singular: simplex). These have many uses, for example as discrete approximations of continuous spaces or manifolds, or abstractly reflecting the structure of information. In either case, we can they study the underlying system using the operations of algebraic topology.
In particular, simplicial topology has applications in sensor networks for things like target evaluation and the analysis of goodness-of-fit of approximations derived from sensors. The mathematics gets quite involved, and for a computer scientist it’s often easier to understand code, so I wrote this small library to help me explore the ideas.
