Let X be a complex analytic manifold, D ⊂ X a free divisor with
jacobian ideal of linear type (e.g. a locally quasi-homogeneous free
divisor), j : U = X − D ֒→ X the corresponding open inclusion, E an
integrable logarithmic connection with respect to D and L the local
system of the horizontal sections of E on U. In this paper we prove
that the canonical morphisms
Ω
•
X(log D)(E(kD)) −→ Rj∗L, j!L −→ Ω
•
X(log D)(E(−kD))
are isomorphisms in the derived category of sheaves of complex vector
spaces for k ≫ 0 (locally on X).Ministerio de Educación y CienciaFondo Europeo de Desarrollo Regiona
