The Taylor series is generated via a unit circle Cauchy integral.

Hi Shel -

it's near new year and ususally I've much time to rethink some more complicated matter in that days. So I thought I'd try again to understand the procedere of the/of your Kneser-solution. I've already downloaded your Kneser.gp and have run it two or three times, but what I am really lacking is the entry-point, the key idea, the door, the basic rationale in which way it differs from the simple regular powerseries approach. (I've also read the paper of Kneser and first time got stuck when he introduced that regions and his handling with that...)
I'm just posting this msg although today I'm just peeking into the forum. I'll have the time to go into the matters possibly tomorrow in the evening or the day after tomorrow.

A "wish you happy new year" to everyone -
