42. Laurent series (Cultivating Complex Analysis 4.4 part 2)

A graduate course on complex analysis, equivalent to an incoming graduate student one-semester (or a bit more) class.

We prove the existence and uniqueness of the Laurent series for holomorphic (analytic) functions defined in an annulus (second part of section 4.4 in the book).

The course is based on the book "Guide to Cultivating Complex Analysis", which is available freely online at
