## Topics related to symmetric functions

Here is an overview of various topics which are related to symmetric functions, but do not fit together with a specific family. Some of the pages give a brief overview of the definitions and notation that is used.

We suggest that the reader is somewhat familiar with algebraic combinatorics, although a few topics is covered under preliminaries below. Furthermore, if you are a PhD student or researcher interested in symmetric functions, join our Facebook group!

### Preliminaries

- Partitions and tableaux
- Permutation matrices and patterns
- $q$-analogs
- Plethysm
- Plane partitions
- Unimodality, realrootedness and stable polynomials
- Representation theory
- Root systems
- Schur positivity
- Models for Littlewood–Richardson coefficients
- Border-strip tableaux and ribbon tableaux
- Diagonal harmonics
- Vertex models and the Yang–Baxter equation
- Lagrange inversion

### Operations on tableaux

- The Robinson–Schensted–Knuth correspondence
- Crystals
- Operations on Young tableaux (Bender–Knuth, promotion, evacuation, jeu-de-taquin)

### Kostka coefficients

- Gelfand–Tsetlin polytopes
- The Kostant partition function
- Kostka–Foulkes polynomials
- Rigged configurations

### Cyclic sieving

### Miscellaneous

- Acyclic orientations and Touchard–Riordan polynomials
- Minor problems related to my research
- Research story: R. Stanley — How the upper bound conjecture was proved
- Research story: J. Haglund — The genesis of the Macdonald polynomial statistic
- R. Stanley -- Enumerative and Algebraic combinatorics in the 1960's and 1970's.

## Software resources

## Suggested books

For an introduction to the topic of symmetric functions and algebraic combinatorics,
I suggest the following books.
Richard Stanley, *Enumerative Combinatorics II* [Sta01],
Lynne Butler, *Subgroup Lattices and Symmetric Functions* [But94],
Bruce Sagan, *The Symmetric Group* [Sag01],
William Fulton, *Young Tableaux* [Ful97] and
Ian Macdonald, *Symmetric functions and Hall polynomials* [Mac95].

Other related books:
David Bressoud, *Proofs and confirmations: the story of
the alternating sign matrix conjecture* [Bre99], which is a very nice reading.

## Files

These files are rather old — I intend to update them some time in the future when the catalog include most of the quasisymmetric families.
