Two stability theorems on plethysms of Schur functions
Rowena Paget, Mark Wildon
The plethysm product of Schur functions corresponds to composing polynomial representations of infinite general linear groups. Finding the plethysm coefficients $\langle s_ν\circ…

The partition algebra and the plethysm coefficients II: ramified plethysm
Chris Bowman, Rowena Paget, Mark Wildon
The plethysm coefficient is the multiplicity of the Schur function in the plethysm product . In this paper we use Schur--Weyl duality between…
