Dans ce travail nous étudions les variétés determinantales essentiellement isolées (EIDS). Ce type de singularité est une généralization de la notion de singularité isolée. La variété determinantale générique M_{m,n}^t est un sous-ensemble des matrices, mxn, tels que le rang est inférieur que t, où t≤m≤n. Une variété X est determinantal si X est définie comme la pré-image d'une fonction holomorphe, F:ℂ^N → M, sur la variété determinantale générique avec la condition codim X=codim M_{m,n}^t. Certains travaux précédents ont étudié les variétés determinantales avec singularité isolée et ils ont défini le nombre de Milnor d'une surface determinantale et la caractéristique évanescente d'Euler.Nous étudions l'ensemble des hyperplans limites d'hy...
