The theory of pseudo-differential operators (which originated as
singular integral operators) was largely influenced by its application
to function theory in one complex variable and regularity properties of
solutions of elliptic partial differential equations. Given here is an
exposition of some new classes of pseudo-differential operators relevant
to several complex variables and certain non-elliptic problems.

The Princeton Legacy Library uses the latest print-on-demand
technology to again make available previously out-of-print books from
the distinguished backlist of Princeton University Press. These editions
preserve the original texts of these important books while presenting
them in durable paperback and hardcover editions. The goal of the
Princeton Legacy Library is to vastly increase access to the rich
scholarly heritage found in the thousands of books published by
Princeton University Press since its founding in 1905.
