All linear symmetries of the SU(3) tensor multiplicities
Briand, Emmanuel; Rosas Celis, Mercedes Helena; Trandafir, Stefan (IOP Science, 2024)The SU(3) tensor multiplicities are piecewise polynomial of degree 1 in their labels. The pieces are the chambers of a ...

On the growth of the Kronecker coefficients
Briand, Emmanuel; Rattan, Amarpreet; Rosas Celis, Mercedes Helena (2017)We study the rate of growth experienced by the Kronecker coefficients as we add cells to the rows and columns indexing partitions. We do this by moving to the setting of the reduced Kronecker coefficients.
