Plethysms of symmetric functions and highest weight representations

Melanie de Boeck, Rowena Paget, Mark Wildon

Let $s_{\nu }\circ s_{\mu }$ denote the plethystic product of the Schur functions $s_{\nu }$ and $s_{\mu }$. In this article we define an explicit polynomial representation corresponding to $s_ν\circ…
