The word is most frequently used with this meaning in Wisconsin and neighboring States on the west, and as the scattered trees are frequently oaks (Quercus nigra, jack-oak, and Q. obtusiloba, post-oak, are the most common species), such openings are often designated as oak-openings. Similar tracts in the more southern States, especially in Kentucky, arc called barrens and oak-barrens.
    • n opening A widening out of a crevice, in consequence of a softening or decomposition of the adjacent rock, which may still remain partly or wholly in its original position, or may have been entirely removed, so as to leave a vacant space of considerable width.

In science:

Since a basis of open sets for the topology of C (R+ ) is formed by open balls of rational radii about piecewise linear functions connecting rational points, there exists a countable family G of open sets such that for every open set G there exists a sequence (On , n ≥ 1) ⊂ G such that 1On ↑ 1G pointwise as n → ∞.
