e strongly influenced by re cent developments in operator theory which affected the choice of topics, proofs and exercises. One of the main features of this book is the large number of new exercises chosen to expand the reader‘s com prehension of the material, and to train him or her in the use of it.

Non Linear Operators,ne of the simplest; the Contraction Mapping Theorem. This theorem is very powerful in that it allows one to prove the existence of solutions to nonlinear integral, differential and functional equations, and it gives a procedure for numerical approximations to the solution. Some of the applications are also included in this chapter.

C. von Fragstein,J. Meingast,H. Hochtors, again the main problem is to solve equations Ax = y for a nonlinear A in a Hilbert or Banach space. Geometrically, this problem means that a certain map or operator B leaves fixed at least one vector x, i.e., x = Bx, where Bx = x + Ax − y, and we have to find this vector. Theorems which establ
