Hilbert Spaceintegrable in the domain ., with the metric as defined in Chap. 3. We could have started earlier with axioms of the Hilbert space and with the investigation of its properties, without first becoming familiar with .(.). However, a different approach has been chosen which is — in our opinion — by far

Operators and Functionals, especially in Hilbert Spaces a given element (as a rule, a function considered as an element of a Hilbert space, e.g., of the space .(.)), and . is the desired solution. To explain the meaning of equation (8.1) in more detail let us present a simple example.

The Method of Steepest Descent. Example method is applicable in the case of bounded operators (Def. 8.13, p. 96), therefore not in the case of differential operators. A typical example of equations to the solution of which it is preferable to apply this method are integral equations.
