Abstract: Sufficient and necessary conditions are provided for a given set to be the zero-set for a suitable given copula. The role of $k$-negations is exploited in this target. We also study several topological properties and the lattice-theoretic structure, and characterize the zero-sets of the class of Archimedean copulas.
