steenroder: A Python package for the computation of persistence Steenrod barcodes
The widespread use in applied topology of the barcode of filtered cellular complexes rests on a balance between discriminatory power and computability. It has long been envision that the strength of this invariant could be increase using cohomology operations. This package computes the recently defined Sqk-barcodes which have been shown to effectively increase the discriminatory power of barcodes on real-world data.
For a complete presentation of these invariants please consult Persistence Steenrod modules by U. Lupo, A. Medina-Mardones and G. Tauzin.
