Math 185: Complex Analysis
Lecture 1, Spring 2016
The official course description from the catalog is:
Analytic functions of a complex variable. Cauchy's integral theorem, power
series, Laurent series, singularities of analytic functions, the residue
theorem with application to definite integrals. Some additional topics such as
We will study the additional structure provided by complex differentiation.
While some parts of complex analysis will look familiar from real analysis,
we will quickly find that in many ways, complex analysis is more rigid.
In many ways, the theme of real analysis is that everything
that can possibly go wrong can go wrong, and that is why we need to write
down rock-solid, rigorous proofs. In contrast, in the complex world,
everything that you could possibly wish for (and more) is true. As an example,
the additional structure provided by complex differentiation
will allow us to compute things like integrals by studying functions just at
specific points, without having to do the hard work of finding
Along the way, we will study other nice properties of complex analytic
functions, such as the maximum principle, Liouville's theorem, and
This course will assume that you have working knowledge of real
analysis from MATH 104 or equivalent. As an advanced upper division course,
you are expected to be able to write mathematically rigorous proofs already,
and teaching this will not be heavily emphasized as it is in MATH 104.
Moreover, many of the concepts will be parallel to those in MATH 104, and it
will be expected that you understand things like formal definitions for
limits, continuity, and
differentiability from the real perspective. In practice, this means that
proofs may be omitted or only sketched briefly if they are identical to
proofs from real analysis. As such, although some strong students have
successfully taken MATH 185 without MATH 104, it is strongly recommended that
you complete MATH 104 before taking this course.
