Linear Operators on a Banach Space,Many of the definitions, theorems and proofs concerning operators in .(., .) carry over verbatim to operators in .(., .), where X and Y are Banach spaces.

Bounded Linear Operators on Hilbert Spaces,in the same way as linear transformations on ℂ. are represented by finite matrices. In this way the chapter may be viewed as a beginning of a theory of infinite matrices. As may be expected, analysis plays a very important role.

Non Linear Operators,tors, 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
