([1, 3, 4], 4, Yes, No, every_open_cover_drawn_from_finite_topology_is_finite)

Compute the number of distinct relative opens. A cover drawn from this finite open-set family has only finitely many distinct members, giving a finite subcover whenever it covers K. This finite-model theorem includes the empty subset; it is not a sampled-cover proof for an infinite topology. The exact result, retaining the requested order, is ([1, 3, 4], 4, Yes, No, every_open_cover_drawn_from_finite_topology_is_finite).

25. The Complete Finite Relative Topology Supplies Compactness

Use ambient carrier Fin(5)={0,…,4}, complete canonical parent_topology=[[], [0, 1], [0, 1, 2], [0, 1, 2, 3], [0, 1, 2, 3, 4], [1]], subset K=[0, 3, 4] and its full induced topology {O intersect K: O is parent-open}, identifying duplicate intersections. Relative opens are subsets of K; ambient witnesses O need not lie in K. Empty K is compact by convention. Give (subset, relative_open_count, compact, empty_subset, certificate).

View answer and explanation

([0, 3, 4], 4, Yes, No, every_open_cover_drawn_from_finite_topology_is_finite)

Compute the number of distinct relative opens. A cover drawn from this finite open-set family has only finitely many distinct members, giving a finite subcover whenever it covers K. This finite-model theorem includes the empty subset; it is not a sampled-cover proof for an infinite topology. The exact result, retaining the requested order, is ([0, 3, 4], 4, Yes, No, every_open_cover_drawn_from_finite_topology_is_finite).

Check that every supplied member is a relative open, compute its union and test whether it covers K. A failing list is not a cover of K; one passing list alone does not certify general compactness.
