Nous étudions les singularités de la variété des hypermatrices dégénérées de taille arbitraire. Notre résultat principal est la classification des composantes irréductibles du lieu singulier. De manière équivalente, nous classifions les composantes irréductibles du lieu singulier de la variété projective duale du plongement de Segre du produit de plusieurs espaces projectifs.
We study the singular locus of the variety of degenerate hypermatrices of an arbitrary format. Our main result is a classification of irreducible components of the singular locus. Equivalently, we classify irreducible components of the singular locus for the projectively dual variety of a product of several projective spaces taken in the Segre embedding.
