The symmetric group

2000
In the previous chapters we have considered the four main methods for the construction of spin eigenfunctions. We shall see in Chapter 9 that the main role of the spin functions in the energy expression is connected to the representation matrices of the symmetric group generated by the spin eigenfunctions.

Skew-symmetric elements in the group algebra of a symmetric group

Algebra and Logic, 1984
Let \(S_ n\) be the symmetric group on \(n\) letters and let \(\rho_ s=\sum_{t\in S_ n}(\text{sign}\;t)t^{-1}st\) for \(s\in S_ n\). The element \(\rho_ s\) depends only (up to a sign) on the conjugacy class of \(s\) and is non-zero if and only if the conjugacy class of \(s\) is determined by a partition with odd pairwise distinct parts. Let \(\lambda =

Chromatic Polynomials and the Symmetric Group

Graphs and Combinatorics, 2004
The author gives a new combinatorial interpretation of the coefficients of chromatic polynomials of graphs in terms of subsets of permutations and introduces a combinatorially defined polynomial associated to a directed graph. He proves that it is related to the chromatic polynomials.

Designs and Representation of the Symmetric Group

Designs, Codes and Cryptography, 2003
A spectral characterization ``à la Delsarte'' is given for colored designs held by codes over non-binary alphabets. The tools include association schemes and also the representation theory of the symmetric group: tableaux, Specht modules, and zonal functions.

Infinite Symmetric Groups.

Ars Comb., 2012
In this work, infinite similarities of permutation groups are investigated by means of new methods. For this purpose, we handle distinct groups on the set of natural numbers and we give the separation of the subgroups of them. Afterwards, we give the matrix representation of this groups.
