Borel isomorphism
WebX) is called a standard Borel space. For simplicity, we will omit the ˙-algebra and write Xinstead of (X;B X). If (X;B X) and (Y;B Y) are Borel spaces, then a map : X!Yis called a Borel isomorphism if it is a bijection and and 1 are Borel measurable. Note that a Borel bijection is automatically a Borel isomorphism (see [Ke95, Corollary 15.2]). WebDec 1, 2008 · We examine the question of how many Boolean algebras, distinct up to isomorphism, that are quotients of the powerset of the naturals by Borel ideals, can be proved to exist in ZFC alone.
