Abstract. For an integer $n\geq1$, an $n$-ary lattice-valued Boolean function is a map from the $n$-th direct power of the 2-element Boolean lattice to a bounded lattice. In terms of closure systems and cuts, we characterize lattice-valued Boolean functions that can be given by linear combinations of elements of the co-domain lattice.
