The universal set is represented by a rectangle. Subsets of this set are represented by closed curves (often circles). A ⊂ € Further subsets are represented by a closed curve within a larger closed curve. Q ⊂ P ⊂ € The intersection of two sets (A & B) is the set of elements that are members of both A & B and is usually shown as a shaded region. A ∩ B The union of two sets (A & B) is the set of all elements contained in A & B. A ∪ B.
The union of a circle and its interior refers to the combination of all points on the circle itself and all points inside the circle. This forms a set that includes both the boundary of the circle and its interior region. In mathematical terms, this union is represented as the circle itself along with all points within the circle, denoted as the closed disk.

This question needs to be rewritten. I can think of union terms for "open/closed" shops, but I am not sure this is what you want.
Yes, Turing recognizable languages are closed under union.
Yes, the Canadian Football League (CFL) is not closed under union operation.
Yes, the set P is closed under union if for any two elements in P, their union is also in P.

In a closed shop, union membership is required. The employer agrees to hire union members only. The employees must remain members of the union in order to remain employed.
