This package provides access to computation of Hilbert bases associated with the space of band structure symmetries (see compatibility_bases, nontopological_bases, and split_fragiletrivial), using Normaliz (which must be installed separately).
The package additionally provides a additional utilities to check the topology of a symmetry vector, using elementary band representations accessed from Crystalline.jl (see calc_detailed_topology and decompose).
The Normaliz library - and in particular its Python bindings, PyNormaliz - are required to use the compatibility_bases and nontopological_bases, which uses PyNormaliz to compute Hilbert bases. This dependency will be installed via PythonCall and CondaPkg.
Note that Normaliz and PyNormaliz are licensed under the GPLv3 (see their license files), but the bindings to the library in this package, SymmetryBases.jl, as well as any other source code in this package, are licensed under the MIT License. This means that code using the Normaliz library via the SymmetryBases.jl bindings is subject to Normaliz's licensing terms. If you distribute a derived or combined work, i.e., a program that links to and is distributed with the Normaliz library, then that distribution falls under the terms of the GPLv3.
