The Stanely-F\'eray-\'Sniady formula for the generalized characters of the Symmetric Group
, 2011 We show that the explicit formula of Stanley-F\'eray-\'Sniady for the characters of the symmetric group have a natural extension to the generalized characters.

A combinatorial realization of Schur-Weyl duality via crystal graphs and dual equivalence graphs [PDF]
, 2008 For any polynomial representation of the special linear group, the nodes of the corresponding crystal may be indexed by semi-standard Young tableaux. Under certain conditions, the standard Young tableaux occur, and do so with weight 0.

Reflection Groups, Braid Groups, Hecke Algebras, Finite Reduction Groups
, 2000 Finite subgroups of GLn(Q) generated by reflections, known as Weyl groups, classify simple complex Lie Groups as well as simple algebraic groups. They are also building stones for many other significant mathematical objects like braid groups and Hecke ...

Higher-order Sugawara operators for affine Lie algebras
, 1989 Let 0 be the affine Lie algebra associated to a simple Lie algebra 0 . Representations of 0 are described by current fields X(Q on the circle T (X e 0 and £ £ T ).

Plethysm, Partitions with an Even Number of Blocks and Euler Numbers
Formal Power Series and Algebraic Combinatorics, 1994 This paper is based on an hour address given at the Sixth Conference on Formal Power Series and Algebraic Combinatorics, held at DIMACS in 1994. It is written primarily for an audience of combinatorialists.

Partitions which are p- and q-core [PDF]
, 2001 Let p and q be distinct primes, n an integer with n > p2q2. Then there is no partition of n which is at the same time p- and q-core.

The largest degrees of irreducible characters of the symmetric group
, 1976 The largest irreducible degrees and the partitions associated with them are tabulated for the symmetric group En for n up to 75. Analytic upper and lower bounds are derived for the largest degree. Introduction.

, 1994 A new family of symmetric functions is considered. These functions are analogous to the classical Schur functions, but depend on an integer modulus p > 2 , as well as on a partition X. In the case where p is prime, certain of these functions are shown to

Twisted immanant and matrices with anticommuting entries
, 2015 This article gives a new matrix function named "twisted immanant," which can be regarded as an analogue of the immanant. This is defined for each self-conjugate partition through a "twisted" analogue of the irreducible character of the symmetric group ...

On perfect isometries and isotypies in alternating groups
, 1997 Perfect isometries and isotypies are constructed for alternating groups between blocks with abelian defect groups and the Brauer correspondents of these blocks.
