Talk:Zero (complex analysis)

From Wikipedia, the free encyclopedia

What is said about entire functions isn't right; no zeroes is equivalent to having a well-defined logarithm without branch points, but any function exp(f(z)) with f entire will do.

This article should surely mention the contour integral way to count zeroes (integrate the logarithmic derivative); Rouché's theorem; and perhaps the construction of functions with given zeroes (infinite products, Blaschke products).

I think this page should be merged with root(mathematics) and a reference to rouché' theorem should be given. other opinions? Hottiger 15:28, 12 April 2006 (UTC)

I like it more this way. If merged, the new root (mathematics) will be unnecessarily biased towards complex analysis in my view. Other views? 23:26, 12 April 2006 (UTC)
