This textbook presents a unified approach to compact and noncompact
Riemann surfaces from the point of view of the so-called L2
$\bar{\delta}$-method. This method is a powerful technique from the
theory of several complex variables, and provides for a unique approach
to the fundamentally different characteristics of compact and noncompact
Riemann surfaces. The inclusion of continuing exercises running
throughout the book, which lead to generalizations of the main theorems,
as well as the exercises included in each chapter make this text ideal
for a one- or two-semester graduate course.
