Irreducible Representations from Group Actions on Trees

Abstract

dc:description.abstract

<p>We study the representations of the symmetric group Sn found by acting on</p> <p>labeled graphs and trees with $n$ vertices. Our main results provide</p> <p>combinatorial interpretations that give the number of times the irreducible</p> <p>representations associated with the integer partitions $(n)$ and (1n) appear</p> <p>in the representations. We describe a new sign</p> <p>reversing involution with fixed points that provide a combinatorial</p> <p>interpretation for the number of times the irreducible associated with the</p> <p>integer partition $(n-1, 1)$ appears in the representations.</p>
