In short, roughly speaking my intention was to write a book on second-order elliptic operators, with the first half of the book, as might be expected, dedicated to function spaces and to linear theory whereas the second, nonlinear half would deal with variational inequalities and non variational obstacle problems, rather than, for example, with quasilinear or fully nonlinear equations (with a few exceptions to which I shall return later).

This book reproduces, with minor changes, the notes prepared for a course given at Brigham Young University during the academic year 1984-1985. However, because the discussion was, generally, carried far enough to introduce the audience to some areas of current research, the book should also be useful to graduate students.

. Thus, most students now obtaining a bachelor's degree in the sciences or engineering have had some exposure to linear algebra. In consequence, many graduate courses in mathematics, applied mathe­ matics, or applications develop certain parts of matrix theory as needed.Matrix Theory: A Second Course Linear algebra and matrix theory are essentially synonymous terms for an area of mathematics that has become one of the most useful and pervasive tools in a wide range of disciplines.

And there is almost never time in the elementary courses to deal with more specialized topics like nonnegative matrices, inertia theorems, and so on. Thus, most students now obtaining a bachelor's degree in the sciences or engineering have had some exposure to linear algebra. In particular, most elementary courses stop at the point of canonical forms, so that while the student may have "seen" the Jordan and other canonical forms, there is usually little appreciation of their usefulness.
