Nov 28, 2012 at 4:37 comment added Steve @Daniel - this "multiple single variable complex analysis" is mostly what I have seen applied - not the scv phenomena which are unique to that field. I think the proof you have offered is awesome though!
Nov 28, 2012 at 1:51 comment added Daniel Moskovich @Ralph Furmaniak: The resolvent has multiple complex variables (z is a vector), but, using a bit of analysis, the linked proof that a matrix has a Jordan normal form translates the problem into multiple problems each involving a single complex variable. Multiple single variable complex analysis ;-)
Nov 27, 2012 at 21:28 comment added Alexandre Eremenko Indeed it seems that functional calculus (taking analytic functions of linear operators) does not fit to any of the "two sources of complex analysis" which I mentioned in my answer. Is this really a "third, independent source" of importance of complex analysis?
Nov 27, 2012 at 19:35 comment added Ralph Furman Thanks for showing this; it's a great proof that I hadn't seen before! However, isn't this just single variable complex analysis?
