Homotopy

A python library for computing homeomorphisms between some common continuous spaces.

Installation

pip install homeotopy

Usage

import homeotopy

points = ...
# create a mapping from the simplex to the surface of the sphere
mapping = homeotopy.homeomorphism(homeotopy.simplex(), homeotopy.sphere())
sphere_points = mapping(points)

rev_mapping = ~mapping
duplicate_points = rev_mapping(sphere_points)

Publishing

Releases are cut manually: run the release workflow from the Actions tab and pick a version bump (patch/minor/major). It runs the checks, bumps the version, builds and publishes to PyPI via trusted publishing (no API token), tags the release, and deploys the docs.
