In the case that X is a metric space, the Borel algebra in the first sense may be described generatively as follows. For a collection T of subsets of X (that is, for any subset of the power set P(X) of X), let • be all countable unions of elements of T • be all countable intersections of elements of T WebBorel sets to Borel sets. Proof. Let f be any continuous, strictly increasing function on some interval. The argumentation above allows us to conclude that fis a homeomorphism. This enables us to show that fmaps Borel sets to Borel sets. To do so, it is su cient to prove that for any continuous function g, the set A= fE: g 1(E) 2Bg

WebThis follows from the observation that images of Borel sets under injective Borel functions remain Borel (this is far from obvious, and takes some descriptive set theory to prove -- see, e.g., 15.A of Kechris' Classical Descriptive Set Theory). [Caveat: Injectivity of the Borel function in the previous observation is essential! WebFor, say, statistical applications there is no empirical difference between Borel sets and a Borel set modified by a null set. The distributions (on the reals) commonly applied can usually be given by a cumulative distribution function and such a function essentially determines the probability of intervals.
