Ah, Thanks for the heads up. I suppose I sort of took that for granted. Would
http://en.wikipedia.org/wiki/Abel%27...mplex_analysis works to show convergence for all z ≠ 1 on the boundary (in particular, at our point i ≠ 1), as the a
n's are monotonically decreasing? Some the a
n, however, are negative...
Trying to take some z
o ≠ 1 with |z
o| = 1 and using some other test (root, comparison, etc.) doesn't seem to work either, though...
