Complex Analysis

Harold V. Mcintosh

When the School of Computation was established at the University of Puebla, it inherited a course on complex variables from an earlier curriculum. Teaching the course was always passed off to the Mathematics Department, but in recent years even they have been reluctant to accept the responsibility. In the meantime, a requirement has arisen for the inclusion of complex analysis in a course on Mathematical Methods related to solid state physics (band gaps, Bloch's theorem, ...). Both of these circumstances have provided the opportunity to review materials last seen in graduate school. There are so many books on complex variable theory in existence that there hardly seems room for still another; nevertheless written material is needed for the entertainment of the students. Consequently these notes cover some of the why's and wherefore's of complex variables; ranging from the role of the cross ratio and the Schwartz derivative to topics such as the Mandelbrot Set, Elliptic Curves, and spectral densities.
