We have the following indirect implication of form equivalence classes:

226 \(\Rightarrow\) 0
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
226 \(\Rightarrow\) 0

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

Howard-Rubin Number Statement
226:

Let \(R\) be a commutative ring with identity, \(B\) a proper subring containing 1 and \(q\) a prime ideal in \(B\). Then there is a subring \(A\) of \(R\) and a prime ideal \(p\) in \(A\) such that

  1. \(B\subseteq A\)
  2. \(q = B\cap p\)
  3. \(R - p\) is multiplicatively closed and
  4. if \(A\neq R\),
then \(R - A\) is multiplicatively closed.

0:  \(0 = 0\).
