Our theory takes a particularly simple form on this space, and it is possible to generalize the results on Borel subsets of N. to general Polish

According to them, a function was to be an arbitrary correspondence between objects without giving any method or procedure by which the correspondence could be established. Since all the specific functions that one studied were determined by simple analytic expressions, Ba

https://doi.org/10.1007/b137577 we introduce trees and the Souslin operation. Trees are also used in several other branches of mathematics such as infinitary combinatorics, logic, computer science, and topology. The Souslin operation is of special importance to descriptive set theory, and perhaps it will be new to some readers.

The relevant results that we shall use to obtain these generalizations are presented in the last section of this chapter.
