TFAE
The abbreviation “TFAE” is shorthand for “the following are equivalent”. It is used before a set of equivalent
conditions (each implies all the others).
In a definition, when one of the conditions is somehow “better” (simpler, shorter, …), it makes sense to phrase the definition with that condition, and mention that the others are equivalent. “TFAE” is typically used when none of the conditions can take priority over the others. Actually proving the claimed equivalence must, of course, be done separately.
