WebApr 6, 2010 · The Borel algebra over ℝ is the smallest σ-algebra containing the open sets of ℝ. (One must show that there is indeed a smallest.) A Borel set of real numbers is an element of the Borel algebra over ℝ. Note that not every subset of real numbers is a Borel set, though the ones that are not are somewhat exotic.

Web2. If C is a σ-algebra, then σ(C) = C. 3. If S ⊂ Rd, or, more generally, S is a topological space, and C is the set of the open sets in S, then σ(C) is called the Borel σ-algebra and denoted B(S). 4.
