PyRigi - software package for rigidity theory

Abstract

PyRigi is a Python package for research in rigidity and flexibility of bar-and-joint frameworks that was initiated at the workshop Code of Rigidity held during the Special Semester on Rigidity and Flexibility at RICAM in Linz, Austria in March 2024. In this talk, we discuss the current status of the package including the documentation, communication tools and possible ways of contributing. As an example of using the package we present a generically rigid graph with two different penny realizations which is a solution to an open problem.
