We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
410 ⇒ 411 | clear |
411 ⇒ 412 | clear |
412 ⇒ 10 |

Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
410: | RC (Reflexive Compactness): The closed unit ball of a reflexive normed space is compact for the weak topology. |
411: | RCuc (Reflexive Compactness for uniformly convex Banach spaces): The closed unit ball of a uniformly convex Banach space is compact for the weak topology. |
412: | RCh (Reflexive Compactness for Hilbert spaces): The closed unit ball of a Hilbert space is compact for the weak topology. |
10: | C(ℵ0,<ℵ0): Every denumerable family of non-empty finite sets has a choice function. |
