2DNumericalSets

Provides python classes to build a tree containing all the 2D numerical semigroups up to a given genus.

Usage

To build a tree of max genus n and check the size of that genus,

In a python 3 interpreter:

>>> from path/to/Tree import tree
>>> t = Tree(n)
>>> print(t.size())	

To view a list of the degrees of vertices at genus g:

>>> print(t.genus(g))

To build a tree with a different ordering function than the default:

In Ordering.py, write a new ordering function that takes in 2 input points and returns True if the first point is less than the second and False otherwise, let's call this function new_ordering_function

Then:

>>> t = Tree(n, new_ordering_function)
