Cochran and Gompf defined a notion of positivity for concordance classes of knots that simultaneously generalizes the usual notions of sliceness and positivity of knots. This positivity essentially amounts to the knot being slice in a positive-definite simply-connected four manifold. We discuss an analogous property for links, and describe relationships with (generalized) Sato-Levine invariants, Milnor's linking invariants, the Conway polynomial, and some modern invariants.
