The representation theory of many families of finite groups can be presented in terms of combinatorial objects. The most famous example is the symmetric groups, where the irreducible complex representations are parametrized by partitions. Other groups, such as the double covers of symmetric and alternating groups, or the infinite family of complex reflection groups, require the use of bar-partitions, or of tuples of partitions with certain properties.
The aim of this project is to develop a fuller understanding of these combinatorial objects, and to use it to better describe the representation theory of groups such as complex reflection groups, or the general linear group.
Of particular interest is the concept of basic set, which can provide some insight in the modular representation theory of finite groups (i.e. over fields of prime characteristic), while in fact working solely over fields of characteristic zero. One major component of this project will be the description of basic sets for various infinite families of finite groups, and their use for producing new information about the decomposition matrices and Brauer characters of these groups.
