A geometric and generating function approach to plethysm

Álvaro Gutiérrez, Rosa Orellana, Franco Saliola +2

Plethysm coefficients ${\mathsf{a}}_{\mu [\nu ]}^{\lambda }$ are the structure coefficients of the plethysm of Schur functions $s_{\mu }[s_{\nu }]={\sum }_{\lambda }{\mathsf{a}}_{\mu [\nu ]}^{\lambda }{s}_{\lambda }$. We study a bivariate gener…
