Installation
The module is distributed on PyPI. You just need to run the following command:
$ sage -pip install mgn --user
The –-user option is optional and allows you to install the module in your user space (and does not require administrator rights).
If this doesn’t work (perhaps because your installation of Sage doesn’t support SSL), click on the download link and extract the files. Open a terminal and go to the extracted directory mgn (which contains the setup.py file). Run:
$ sage -pip install .
mgn Package
The mgn package contains two modules for computations on the moduli space of curves: strataalgebra and topintersections.
strataalgebra
This module computes product in the strata algebra. It also contains some of A. Pixton’s code to compute FZ relations. Read the documentation.
To see if it is installed, try:
sage: from strataalgebra import * sage: StrataAlgebra(QQ, 1, (1,2)) Strata algebra with genus 1 and markings (1, 2) over Rational Field
topintersections
This module computes top intersections. Read the documentation.
To see if it is installed, try:
sage: from topintersections import * sage: space(1, 2) [1] psi1 [2] psi2 [3] ka1 [4] ka2 [5] ch1 [6] irr [7] Dg0m1_2 [8] la1 Mbar_1_2 sage: intnum(psi1*psi2) Computing the intersection of psi1*psi2 over Mbar_1_2... 1/24
