Create viable free open source software for arithmetic geometry research
Purple SAGE is research-oriented mathematics software based on Sage.
The main goal is to create viable free open source
software for arithmetic geometry research.
The lead developer is William Stein.
PSAGE Python Library
The PSAGE Python library, which
is hosted at Google
code is a new Python library. It can be installed into any recent
copy of Sage, or installed into the PSAGE distribution (see below).
The PSAGE distribution is a stripped down version of the Sage
distribution. For example, it does not include anything that relies
on Fortran or LISP. It's main design constraint is that it should
offer enough capabilities that the PSAGE library (see above) works in
it. The goals are that the library get smaller, and that all the
multi-process pexpect code disappears (so PARI, GAP and Singular are
used *only* through Cython).
