- Dear Messrs PRATT , BUDNIK et al,
-
- I will construct two examples of Set-Theories C and U such that
- in C the set {1,2} is countable and in U the set {1,2} is uncountable!
-
-
- As usual, {a,b,...} will stand for a set whose elements are a, b,...
- and the set {{a}, {a,b}} will be denoted by (a,b) (ordered pair). So,
- the elements of the set (a,b) are {a} and {a,b}.
-
-
- The sets of my set-theoretical model C are given below:
-
-
- { } denoted by 0, {0} denoted by 1, {0,1} denoted by 2
-
- {{0},{0,1}} which is same as {1,2}, {1}, {{1},{1,2}} and
-
- {{{0},{0,1}}, {{1},{1,2}}} denoted by {(0,1), (1,2)} = F
-
-
- So, the entire set-theoretical model C has the ABOVE SETS - NOTHING MORE.
- Of course, it is not a model for ZF set-theory. However, it is a model
- for some set-theory. The union of two sets of the Model may or may not
- exist in the Model. The intersection of two sets may or may not exist,
- the powerset of a set may or may not exist. The Cartesian product of
- two sets may or may not exist. The singleton of a set may or may not exist
- in the Model, etc., etc It is a very, very, very weak set-theoretical model
- BUT IT IS A SET-THEORETICAL MODEL !
-
-
- THEOREM. In model C the set {1,2} is COUNTABLE.
-
- PROOF. Because in C there exists the Function F = {(0,1), (1,2)}
- which establishes a one-to-one correspondence between the na-
- tural number 2 and the set {1,2} (and every mentioned set in the
- proof is a set of C). But this means that {1,2} is
- COUNTABLE IN Model C (in fact, countable by the natural number 2)
-
-
- Next, I introduce my set-theoretical model U which has the same sets as
- model C, except that it does not have the set {{{0},{0,1}}, {{1},{1,2}}}
-
-
- Using notations introduced in C, the sets of my set-theoretical model
- U are given below:
-
- { } , {0}, {0,{0}}, {1}, {0,1}, {1, 2}
-
- Again, C is a very, very, very, very weak set-theoretical model BUT IT
- IS A SET-THEORETICAL MODEL!
-
-
- THEOREM. In model U the set {1,2} is UNCOUNTABLE.
-
- PROOF. Because in U there is no function F which establishes a
- one-to-one correspondence between a natural number and the set {1,2}.
-
-
- P.S. This is the undressing of the LOW-SKO. paradox. I have also
- an undressing proof for the LOW-SKOLEM THEOREM. But I have no time
- to undress so many people. However, I may undress two more things:
- " Derivation of addition of velocities in Relativity"
- and " Derivation of Various non-Euclidean Geometries".
- But maybe I won't do these - it may be too provocative ! Remember
- (A1) ! - reaction to provocation and H-bomb !!
-
- Withe best wishes and regards,
-
