bigger 0.1.0

For studying big mapping classes

Bigger is a program for computing big mapping classes and their actions on laminations via ideal triangulation coordinates.

Bigger officially supports Python 3.5 – 3.8.

Quickstart

Bigger is available on PyPI, so it can be installed via:

$ pip install bigger --user --upgrade

Once installed, try it inside of Python:

>>> import bigger
>>> S = bigger.load.ladder()  # The infinite-genus two-ended surface
>>> a = S.triangulation({(0, 5): -1})  # An arc
>>> a
(0, 5): -1
>>> a == a
True
>>> b = S('shift.shift')(a)  # Shift everything down twice
>>> a == b
False
>>> b
(2, 5): -1
>>> S('SHIFT.shift')(a) == a  # Shift and then shift back
True
>>> S('shift.b.b.b.b')(a)  # Twist then shift
(1, 6): 2, (1, 5): 3
