Implications

We have the following indirect implication of form equivalence classes:

124 \(\Rightarrow\) 124
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
124 \(\Rightarrow\) 124 Hilbertraume mit amorphen Basen (English summary), Brunner, N. 1984a, Compositio Math.

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

Howard-Rubin Number Statement
124:

Every operator on a Hilbert space with an amorphous base is the direct sum of a finite matrix and  a  scalar operator.  (A set is amorphous if it is not the union of two disjoint infinite sets.)

124:

Every operator on a Hilbert space with an amorphous base is the direct sum of a finite matrix and  a  scalar operator.  (A set is amorphous if it is not the union of two disjoint infinite sets.)
