Science
It follows that, under the propositions-as-monotypes interpretation, the proposition \({\forall i \inn I}\ {\exists j \inn J}\ M_{ij}\) is interpreted as the singleton and the proposition \({\exists f \inn J^I}\ {\forall i \inn I}\ M_{if(i)}\) as the singleton Under the propositions-as-monotypes interpretation AC would be construed as asserting the existence of an isomorphism between (1) and (2).
Science

Science

Expert writing Tips
Best practice
Use "under the proposition" when you want to clearly state that a condition, rule, or understanding is governed by a specific proposition or idea. Ensure the proposition is clearly defined or referenced in the surrounding text.
Common error
Avoid using "under the proposition" when you actually mean "supporting the proposition". The former indicates governance, while the latter suggests agreement or advocacy. For example, don't say "They campaigned under the proposition" if they were simply campaigning in favor of it; instead, use something like "They campaigned in support of the proposition."
