Invariance properties for coefficients of symmetric functions
(2016)
We show that several of the main structural constants for symmetric functions (Littlewood-Richardson coefficients, Kronecker coefficients, plethysm coefficients, and the Kostka-Foulkes polynomials) share invariance properties ...

Generating partial Hadamard matrices as solutions to a Constraint Satisfaction Problem characterizing cliques
(2017-07)
A procedure is described looking for partial Hadamard matrices, as cliques of a particular subgraph Gt of Ito’s Hadamard Graph Δ(4t) [9]. The key idea is translating the problem of extending a given clique Cm to a larger ...
