We prove the conjecture of J. Brasselet, M. Goresky, and R. MacPherson on the isomorphism between L cohomology and intersection cohomology for a stratified space with a Riemannian metric and conical singularities. We prove the extension of this conjecture to spaces with /-horn singularities, where f{r) is any C°° nondecreasing function. We study the L Stokes property which states that the minimal closed extension of d acting on if forms coincides with the maximal one. We prove that it implies the Borel-Moorse duality between the complexes of L forms and I? forms. We also prove the converse for spaces with /-horn singularities under the condition that the integral /0 £ f(r)~ dr diverges.
