Point Selections and Weak ε-Nets for Convex Hulls
One of our results: let X be a finite set on the plane, 0 < g < 1, then there exists a set F (a weak g-net) of size at most 7/e 2 such that every convex set containing at least e\X\ elements of X intersects F. Note that the size of F is independent of the size of X.

متن کاملPointfree Pseudocompactness Revisited
We give several internal and external characterizations of pseudocompactness in frames which extend (and transcend) analogous characterizations in topological spaces. In the case of internal characterizations we do not make reference (explicitly or implicitly) to the reals.
متن کاملUltrafilters, monotone functions and pseudocompactness
In this article we, given a free ultrafilter p on ω, consider the following classes of ultrafilters: (1) T (p) the set of ultrafilters Rudin-Keisler equivalent to p, (2) S(p) = {q ∈ ω∗ : ∃ f ∈ ω, strictly increasing, such that q = f β(p)}, (3) I (p) the set of strong Rudin-Blass predecessors of p, (4) R(p) the set of ultrafilters equivalent to p in the strong Rudin-Blass order, (5) PRB(p) the s...
متن کاملSelections
It was not until the sixteenth century that dead bodies were submitted to medico-legal investigation. The horror which human dissections inspired in the ancients, and the religious awe with which they beheld the mortal wreck of their fellows, not only retarded the progress of anatomy and physiology, but excluded the light of medicine from the researches of the forum. The Jewish law, indeed, con...
