Kernels, is the set of nonnegative real numbers, and H is the unit interval, i.e., the set of real numbers between 0 and 1 inclusive; in all these cases the measure is Lebesgue measure defined on the class of all Borei sets. This notation (including ., ., ., and .) will be fixed throughout.

Boundedness,the domain of Int .. Another possibility: a kernel may or may not be closed. (Problem 3.12 can therefore be expressed this way: is it true that if dom . is closed, then . is closed?) A notational possibility for bounded kernels (that is hereby adopted): write ‖.‖ instead of ‖Int .‖.
