Given a closed subspace $Y\subset X$ of pure codimension p>0, we consider the sheaf of local algebraic cohomology $H^p_{[Y]}({\cal O}_X)$, and ${\cal L}(Y,X)\subset H^p_{[Y]}({\cal O}_X)$ the intersection homology D_X-Module of Brylinski-Kashiwara. We give here an algebraic characterization of the spaces Y such that L(Y,X) coincides with $H^p_{[Y]}({\cal O}_X)$, in terms of Bernstein-Sato functional equations.16 pagesAlgebraic Geometry32S40 ; 32C38 ; 32C40 ; 32C25 ; 14B05text
