WebMay 7, 2015 · It is not true in general that an acyclic sheaf is soft, i.e. vanishing higher cohomology doesn't imply that F is soft. The De Rham-Weil theorem states that if 0 → F → A ∙ is an acyclic resolution of F, then H k ( X, F) ≅ H k ( A ∙ ( X), F). (I assume this is the version you are referring to).
