I'm reading through a probability text and it uses the term "parries" in an epsilon / delta proof. I've never seen this word used before and I certainly don't understand what it is supposed to mean. Here is the verbiage:
Let $\varepsilon > 0$, we thus need to show $\lim_{n \rightarrow \infty} P(|f(x_n) − f(x)| > \varepsilon) = 0$. To this end, let $m \geq 1$. As $[−(m + 1), m + 1]$ is compact, $f$ is uniformly continuous on this set. Choose $\delta > 0$ such that $\delta$ parries $\varepsilon$ for this uniform continuity of $f$ ...
What does "Choose $\delta > 0$ such that $\delta$ parries $\varepsilon$..." mean exactly?
Thank you.
