Complex Made Simple
Share this pageDavid C. Ullrich
Perhaps uniquely among mathematical topics,
complex analysis presents the student with the opportunity to learn a
thoroughly developed subject that is rich in both theory and
applications. Even in an introductory course, the theorems and
techniques can have elegant formulations. But for any of these
profound results, the student is often left asking: What does it
really mean? Where does it come from?
In Complex Made Simple, David Ullrich shows the student how to
think like an analyst. In many cases, results are discovered or
derived, with an explanation of how the students might have found the
theorem on their own. Ullrich explains why a proof works. He will
also, sometimes, explain why a tempting idea does not
work.
Complex Made Simple looks at the Dirichlet problem for harmonic
functions twice: once using the Poisson integral for the unit disk and
again in an informal section on Brownian motion, where the reader can
understand intuitively how the Dirichlet problem works for general
domains. Ullrich also takes considerable care to discuss the modular
group, modular function, and covering maps, which become important
ingredients in his modern treatment of the often-overlooked original
proof of the Big Picard Theorem.
This book is suitable for a first-year course in complex analysis. The
exposition is aimed directly at the students, with plenty of details
included. The prerequisite is a good course in advanced calculus or
undergraduate analysis.

Reviews & Endorsements
This is an excellent book for a first-year graduate student doing a course in complex analysis. ...students will enjoy and profit from Ullrichs careful explanation of why the theorems work the way they do and also sometimes why seemingly nice ideas that promised to work do not (but often can be patched so that they do). ... In short, Ullrich has managed to write a book about a classical subject that is unusual because its exposition is aimed directly at students, not instructors. I strongly recommend this book to everyone.
-- MAA Reviews
In general, the entire exposition stands out by its particular didactic features, by its expository mastery, and by its lucid style helping students grasp both the matter and the beauty of complex function theory profoundly. The prerequisites are kept to minimum, or recalled in the appendices, whereas the scope of the book is remarkably wide. Altogether, the current book offers a nearly irresistible invitation to the fascinating subject of complex analysis.
