Tree Representations of Non-symmetric Group-Valued Proximities
Let X be a finite set and let d be a function from X × X into an arbitrary group G. An example of such a function arises by taking a tree T whose vertices include X, assigning two elements of G to each edge of T (one for each orientation of the edge), and setting d(i, j) equal to the product of the elements along the directed path from i to j. We characterize conditions when an arbitrary functi...
متن کاملIrreducible Representations of the Symmetric Group
We construct the Specht modules and prove that they completely characterize the irreducible representations of the symmetric group. We will prove certain properties of these representations using combinatorial tools (such as calculating the dimension using Hook’s length formula). Only an introductory knowledge of group theory and linear algebra will be assumed and representation theory concepts...
متن کاملThe Representations of the Symmetric Group
In this paper we classify the irreducible representations of the symmetric group Sn and give a proof of the hook formula for the dimension of each irreducible. 1. The Irreducible Representations of Sn We construct the irreducible representations of the symmetric group. The number of irreducible representations of Sn is the number of conjugacy classes of Sn, which is the number of partitions of ...
متن کاملIrreducible Representations of the Symmetric Group
The intent of this paper is to give the reader, in a general sense, how to go about finding irreducible representations of the Symmetric Group Sn. While I would like to be thorough toward this end, I fear we must assume some results from Wedderburn Theory that will be given without proof because although they are important, proving and discussing these results is not in the scope of this paper....
متن کاملPfaffians and Representations of the Symmetric Group
Pfaffians of matrices with entries z[i, j]/(xi + xj), or determinants of matrices with entries z[i, j]/(xi−xj), where the antisymmetrical indeterminates z[i, j] satisfy the Plücker relations, can be identified with a trace in an irreducible representation of a product of two symmetric groups. Using Young’s orthogonal bases, one can write explicit expressions of such Pfaffians and determinants, ...
