Add to ORKGAbstract. Singularities of rank-two reflexive sheaves on smooth three-folds are studied. They must be isolated, and several numerical invariants are attached to them. It is shown that it is possible to eliminate the singularities by taking quadratic transformations and suitable transforms of the sheaf. 1
