Let the ε neighborhood of 00 be the set of all s with | s | > 1 / ɛ and the ε
neighborhood of a point s , in RN consist of s with 18 - Sol < . Let fé ( s ) = f ( s ) if
s is not in the ε neighborhood of any singular point , and otherwise let fe ( s ) = 0 .
Then for ...

Let f be a function analytic in a domain U which , when taken together with a finite
number of exceptional points p , includes a neighborhood of o ( T ) and a
neighborhood of the point at infinity . Suppose that each exceptional point p
satisfies E ...
