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 ...

Commutation and normal ordering for operators on symmetric functions
Briand, Emmanuel; McNamara, Peter R. W.; Orellana, Rosa C.; Rosas Celis, Mercedes Helena (2019)We study the commutation relations and normal ordering between families of operators on symmetric functions. These operators ...

Invariance properties for coefficients of symmetric functions
Briand, Emmanuel; Orellana, Rosa C.; Rosas Celis, Mercedes Helena (2016)We show that several of the main structural constants for symmetric functions (Littlewood-Richardson coefficients, Kronecker ...

Milne's volume function and vector symmetric polynomials
Briand, Emmanuel; Rosas Celis, Mercedes Helena (Elsevier, 2009-05)The number of real roots of a system of polynomial equations fitting inside a given box can be counted using a vector ...

On the Sn-module structure of the noncommutative harmonics
Briand, Emmanuel; Rosas Celis, Mercedes Helena; Zabrocki, Mike (Elsevier, 2008-08)Using the a noncommutative version of Chevalley’s theorem due to Bergeron, Reutenauer, Rosas, and Zabrocki we compute the ...

Rectangular symmetries for coe cients of symmetric functions
Briand, Emmanuel; Orellana, Rosa; Rosas Celis, Mercedes Helena (The Electronic Journal of Combinatorics, 2015-07-31)We show that some of the main structural constants for symmetric functions (Littlewood-Richardson coe cients, Kronecker ...

Reduced Kronecker coefficients and counter-examples to Mulmuley's strong saturation conjecture SH
Briand, Emmanuel; Orellana, Rosa C.; Rosas Celis, Mercedes Helena (Springer, 2009-12)We provide counter–examples to Mulmuley’s strong saturation conjecture (strong SH) for the Kronecker coefficients. This ...

The stability of the Kronecker products of Schur functions
Briand, Emmanuel; Orellana, Rosa C.; Rosas Celis, Mercedes Helena (Elsevier, 2011-04-01)In the late 1930’s Murnaghan discovered the existence of a stabilization phenomenon for the Kronecker product of Schur ...
