a library for working with zero divisor graphs of commutative semigroups
Zero Divisor Graph math library
This is a pure python library for working with zero divisor graphs of commutative semigroups. The primary purpose is to automate the task of checking if a given graph is a zero divisor graph and for what possible semigroups.
pip3 install zero-divisor-graph
You can also retrieve from source at https://github.com/Paulcappaert/zero-divisor-graph
first start python3 in a terminal window and import the ZeroDivisorGraph object
python3 >>> from zdg.zdg import ZeroDivisorGraph as ZDG
You can create a zero divisor graph from edges as such. the vertices can be named whatever you want.
>>> example1 = ZDG((1, 2), (2, 3)) >>> example2 = ZDG(('a', 'b'), ('b', 'c'))
You can print all of the semigroups from a zero divisor graph as such
>>> semigroups = example1.semigroups() >>> for s in semigroups: ... print(s.caley_table())
