Protected since the 1970s, giraffes cohabit with humans in cultivated landscapes. This may not have appeared to pose many problems in the past, but the relationship… (More)
We propose a new approach to study the Kronecker coefficients by using the Schur–Weyl duality between the symmetric group and the partition algebra. Résumé. Nous proposons une nouvelle approche pour l'´ etude des coéfficients de Kronecker via la dualité entre le groupe symétrique et l'algèbre des partitions.
