# Combinatorial Representation Theory

@article{Barcelo1997CombinatorialRT, title={Combinatorial Representation Theory}, author={H{\'e}l{\`e}ne Barcelo and Arun Ram}, journal={Oberwolfach Reports}, year={1997}, volume={7}, pages={799-882} }

We attempt to survey the field of combinatorial representation theory, describe the main results and main questions and give an update of its current status. We give a personal viewpoint on the field, while remaining aware that there is much important and beautiful work that we have not been able to mention.

We give a polynomial basis of each irreducible representation of the Hecke algebra, as well as an adjoint basis. Decompositions in these bases are obtained by mere specializations.

### A Survey of Representation Stability Theory

- Mathematics
- 2016

In this survey article we summarize the current state of research in representation stability theory. We look at three different, yet related, approaches, using (1) the category of FI-modules, (2)…
