This is a site meant to let you easily compute the B-Symmetric Chromatic Function.
If you're unfamiliar with the B-Symmetric Chromatic Function, perhaps try looking at
Dr. Sergei Chmutov's Presentation
or
Rushil Raghavan's Presentation
to learn more if you're interested.
Currently, the built in graphs are:
- create_path(number_of_vertices, signs) - Creates a path graph
- create_star(number_of_vertices, signs) - Creates a star graph
- create_cycle(number_of_vertices, signs) - Creates a cycle graph
I'll probably add more built in functions, or a compendium of examples that we can easily modify.
I've also added some utilities for working with signed posets as root systems.
Here is a short list of some of the available things:
- list_acyclic_orientations(signedGraph) - Returns a set of SignedPosets with the acyclic orientations
- SignedPoset(number_of_vertices, roots [as vectors]) - Constructor for a signed SignedPoset
- SignedPoset.get_jordan_holder_set() - Computes the Jordan-Holder set of the poset as a list of Weyl Group elements
- SignedPoset.plot_digraph() - Plots the SignedPoset
Sincerely,
Torey Hilbert
