WebA fixed lattice has the [n]-density property if n is large enough. The density of a generator U of a union-closed family of sets L containing the empty set is estimated. The estimate depends only on the local properties of L at U. If L is generated by sets of size at most two, then there is a generator U of L with estimated density at most 1/2.

Let ∏ i ∈ I A i where { A i } i ∈ I is a family of sets. For a subset B ⊂ A, let B i = p i ( B) for each i ∈ I. Prove that B ⊂ ∏ i ∈ I B i. I am trying to prove this question. I am very confused because in ∏ i ∈ I B i, the elements are functions but in B, the elements are not functions?
