2. An example of a content that is not a measure on a ?-algebra is the content on all subsets of the positive integers that has value 1 / 2 " n " on the integer " n " and is infinite on any infinite subset.
3. Simpson introduced an alternative definition of bqo in terms of Borel maps [ \ omega ] ^ { \ omega } \ to Q, where [ \ omega ] ^ { \ omega }, the set of infinite subsets of \ omega, is given the usual ( product ) topology.
4. Because no one-to-one pairing can be made between countable and uncountable sets, rooms at the hotel cannot be made for all of these guests, although any countably infinite subset of them can still be accommodated  for example, the set of guests whose addresses terminate in an infinitely repeating sequence, corresponding to a rational number.
5. Once you've included it, all of its supersets are included and all subsets of its complement are excluded, and all of its intersections with sets already included are included, and all unions of its complement with sets already excluded are excluded, etc .

7. That theorem implies that there is some countably infinite subset of the real numbers, whose members we will call " internal numbers ", and some countably infinite collection of sets of internal numbers, whose members we will call " internal sets ", such that the domain consisting of internal numbers and internal sets satisfies exactly the same first-order sentences as are satisfied by the domain of real numbers and sets of real numbers.
8. Any theory is either the theory of all sets of cardinality in " N " for some " finite " subset " N " of the non-negative integers, or the theory of all sets whose cardinality is not in " N ", for some " finite or infinite " subset " N " of the non-negative integers . ( There are no theories whose models are exactly sets of cardinality " N " if " N " is an infinite subset of the integers . ) The complete theories are the theories of sets of cardinality " n " for some finite " n ", and the theory of infinite sets.
9. More interesting is the position that, given infinite universes, there should then exist an infinite subset of universes differing from each other " only in the apparent current date and time "-thus one could go " sideways " to a universe in with its current date in the " past ", which is really currently existing the universe you started in, and then a side-step to a current universe " from that parallel universe " would show the effect of such a change, but without affecting one's own existence ( possibly then anomalous, but " not " contravening any other laws ) . " Time travel " within a single current universe has more problems, but " apparent time travel " to an " alternate universe " would seem a lot easier to hand-wave . talk ) 13 : 28, 17 June 2016 ( UTC)
