Let An k denote the affine space of dimension n over a field k, let XCA n k be an arrangement of linear subvarieties. Set R ¼ k½x1, y, xn and let ICR denote an ideal which defines X. In this paper we study the local cohomology modules Hi I ðRÞ: ¼ indlimj Exti RðR/Ij, RÞ, with special regard of the case where the ideal I is generated by monomials.
