New description:
Implements (standard) tableaux of shape a !PartitionTuple. That is,
tableau with shape a tuple of partitions, together with standard functions
for these objects. These objects arise naturally in algebraic
combinatorics, such as in the representation theory of the cyclotomic
Hecke algebras of type G(r,1,n) and (hence) in the categorification of the
irreducible highest weight representations (and their canonical bases) of
the (quantum) affine special linear groups.[[BR]][[BR]]This patch
implements !TableauTuples and !StandardTableauTuples and basic methods for
them. The idea is that these classes should naturally extend the
corresponding Tableaux classes, which are in bijection with 1-tuples of
tableaux. As with !PartitionTuples, the !TableauTuple classes return
honest Tableaux whilst still recognising them as being !TableauTuples.
Both Tableaux and !TableauTuples classes have a component() method which
returns the list of components which allows loops such as
{{{
for s in t.components():
do X
}}}
where t is a !TableauTuple (or Tableau). With this modification is it
possible to write code which will behave the same for both classes.
Whenever they were meaningful, I have implemented existing functions for
tableaux for the tableau tuples. For example, there are iterators for
!StandardTableauTuples, you conjugate !TableauTuples, take teir shape and
size, compute words, act on them....[[BR]][[BR]]The patch implements the
following classes:[[BR]] * !TableauTuples(!UniqueRepresentation,
Parent):[[BR]] * !TableauTuples_all(!TableauTuples):[[BR]] *
!TableauTuples_level(!TableauTuples):[[BR]] *
!TableauTuples_size(!TableauTuples):[[BR]] *
!TableauTuples_level_size(!TableauTuples):[[BR]] *
!StandardTableauTuples(!TableauTuples):[[BR]] *
!StandardTableauTuples_all(!StandardTableauTuples):[[BR]] *
!StandardTableauTuples_level(!StandardTableauTuples):[[BR]] *
!StandardTableauTuples_size(!StandardTableauTuples):[[BR]] *
!StandardTableauTuples_level_size(!StandardTableauTuples):[[BR]] *
!StandardTableauTuples_shape(!StandardTableauTuples):[[BR]][[BR]]Unfortunately,
I haven't been able to up[load the patch to the patch server. When I tried
something when wrong. Will keep trying...
