The Molecular Species $\mathbf{C}_α$: Geometric Realization and a Closed Formula for Kronecker Coefficients
Year: 2026
Type: preprint
Abstract: In this paper we first introduce the \emph{infinite multi-row periodic pattern of shape $α$} as a geometric realization of $\mathbf{C}_α$. We then give an explicit formula for the coefficients $b^λ_{α,β}$ appearing in the species decomposition \[ \mathbf{C}_α\times \mathbf{C}_β = \sum_{λ\vdash n} b^λ_{α,β}\,\mathbf{C}_λ. \]
