#9267: Update the charge statistic on words
-----------------------------+----------------------------------------------
Reporter: jbandlow | Owner: sage-combinat
Type: defect | Status: new
Priority: major | Milestone: sage-4.4.4
Component: combinatorics | Keywords: words, charge, cocharge
Author: | Upstream: N/A
Reviewer: | Merged:
Work_issues: |
-----------------------------+----------------------------------------------
The following behavior is currently in sage:
{{{
sage: w = Word([1,2,3,1,2])
sage: w.charge()
0
}}}
This is inconsistent with the definition one usually finds in the
literature, which would give the charge of this word as 2. (see
Macdonald's book, for example).
The goal of this ticket is to fix this bug, add a cocharge statistic, and
extend the definition to words without partition content.
