If we're judging by the way anon wrote it, yes.
But [math]a \in (I:f^n) \rightarrow a = gf^n \rightarrow a = (gf)f^{n-1} \rightarrow a \in (I : f^{n-1} )[/math], so it trivializes to [math](I: f)[/math], and I'm thus assuming he forgot a for all in the definition.
Also because I distantly recall seeing this stuff before.
