Implications

We have the following indirect implication of form equivalence classes:

363 \(\Rightarrow\) 93
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
363 \(\Rightarrow\) 368 clear
368 \(\Rightarrow\) 93 Sur quelques probl`emes qui impliquent des fonctions non-mesur-ables, Sierpi'nski, W. 1917, C. R. Acad. Sci. Paris S'er. A-B

Here are the links and statements of the form equivalence classes referenced above:

Howard-Rubin Number Statement
363:

There are exactly \(2^{\aleph_0}\) Borel sets in \(\Bbb R\). G. Moore [1982], p 325.

368:

The set of all denumerable subsets of \(\Bbb R\) has power \(2^{\aleph_0}\).

93:

There is a non-measurable subset of \({\Bbb R}\).
