Part explanation of important recent work, and part introduction to some
of the techniques of modern partial differential equations, this
monograph is a self-contained exposition of the Neumann problem for the
Cauchy-Riemann complex and certain of its applications. The authors
prove the main existence and regularity theorems in detail, assuming
only a knowledge of the basic theory of differentiable manifolds and
operators on Hilbert space. They discuss applications to the theory of
several complex variables, examine the associated complex on the
boundary, and outline other techniques relevant to these problems. In an
appendix they develop the functional analysis of differential operators
in terms of Sobolev spaces, to the extent it is required for the
monograph.
