About this pip-installable distribution

This pip-installable source distribution passagemath-libbraiding provides an interface to libbraiding <https://github.com/miguelmarco/libbraiding>_, a library to compute several properties of braids, including centralizer and conjugacy check.

What is included

• sage.libs.braiding <https://github.com/passagemath/passagemath/blob/main/src/sage/libs/braiding.pyx>_

Examples

::

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-libbraiding[test]" ipython

In [1]: from sage.all__sagemath_libbraiding import *

In [2]: from sage.libs.braiding import conjugatingbraid

In [3]: B = BraidGroup(3); b = B([1,2,1,-2]); c = B([1,2])

In [4]: conjugatingbraid(b,c)
Out[4]: [[0], [2]]
