# Lectures on Counterexamples in Several Complex Variables

*John Erik Fornæss; Berit Stensønes*

AMS Chelsea Publishing: An Imprint of the American Mathematical Society

Counterexamples are remarkably effective for understanding the meaning,
and the limitations, of mathematical results. Fornæss and
Stensønes
look at some of the major ideas of several complex variables by
considering counterexamples to what might seem like reasonable variations
or generalizations. The first part of the book reviews some of the basics
of the theory, in a self-contained introduction to several complex
variables. The counterexamples cover a variety of important topics: the
Levi problem, plurisubharmonic functions, Monge-Ampère equations, CR
geometry, function theory, and the \(\bar\partial\) equation.

The book would be an excellent supplement to a graduate course on several
complex variables.
