Sage Days 49 Coding Sprint Projects
For the main Sage Days 49 page go here
Below is a list of proposed projects. Please edit and add your projects!
Combinatorics
Implementing Stanley chromatic symmetric function for posets
Mathieu, Eric, Alejandro, Chris
Implementing boards for rook placements, Le diagrams (#14127)
- implementing Le diagrams
- include CombinatorialMaps if possible
- adding documentation and doctests
Alejandro, Kevin (testing/doctests)
Flow polytopes from permutation matrices and alternating sign matrices (#14654)
Jessica, Alejandro
Implementation of k-tableaux and kcharge
Anne, Jennifer, Mike
Combinatorial actions and orbit averages on posets, order polytopes, and rational functions
Tom Roby, Darij, Jessica, Kevin
Combinatorial Species
Martin Rubey, Thursday and Friday only
- code cleanup
- generation of unlabelled objects for composition and functorial composition via a group action framework
- multisort species (multivariate formal power series would be useful for that)
- add code by Andrew for Gamma-species
- support operations from symmetric function code for cycle index series
Conclude OEIS ticket #10358 (rebase after #13701, last doctests, and make urls clickable from the notebook
ThierryMonteil
More switches from CombinatorialClass to category framework
Travis
Implement LaTeX options for parking functions
Mike

beef up NSym/QSym functionality - dual bases, quasi-Schur and dual's, basis by Pieri rule, map to free algebra, P-partitions, Hazewinkel's lambda-Lyndon basis, quasi-Schurs
Mike, Matthieu Deneufchâtel, Darij, Chris
Finish affine symmetric group patch
Tom, Chris
