Query: Complete intersections primitive structures on space curves   A multiple (loc. Cohen Macaulay) structure, X, on a space curve C in P3 is
said to be primitive if X is locally contained in a smooth surface. We give
numerical conditions for C to be a "primitive" set theoretic complete
intersection (i.e. to have a primitive multiple structure which is a complete
intersection).
