Hi all.
I need some help to understand this, what should be simple, sentence:
Since a \to b as c \downarrow 0 it was shown that...
What does the down arrow mean? It can not mean "goes to", since c is a constant. I'm thinking it is meaning something like "c is a small positive number" ??
Thanks.

One last thing: What does "from the right" mean? Does "from the right" equal the positive numbers, and "from the left" equals negative numbers?
Edit:
That makes sense, since c never is negative.
Thanks for your help.
