WebThe free part of a Borel system is the subsystem obtained by restriction to the nonperiodic points, and a full subset is an invariant subset of measure one for every invariant Borel probability measure. Two Borel systems are almost-Borel isomorphic if they are Borel isomorphic after restriction to full subsets of their free parts.

WebIn Srivastava, "A course on Borel sets", he considers the space of B ( X, Y) ⊆ M ( X, Y) of Baire functions, i.e. continuous functions and closed under pointwise limit. Then he states the Lebesgue – Hausdorff theorem that B ( X, Y) = M ( X, Y) for metrizable X. But I haven't found a theorem or note in the book that says that B ( X, Y) is ...

Let X be a topological space. The Borel space associated to X is the pair (X,B), where B is the σ-algebra of Borel sets of X. George Mackey defined a Borel space somewhat differently, writing that it is "a set together with a distinguished σ-field of subsets called its Borel sets." However, modern usage is to call the distinguished sub-algebra the measurable sets and such spaces measurable spaces. The reaso…
In mathematics, a Borel isomorphism is a measurable bijective function between two measurable standard Borel spaces. By Souslin's theorem in standard Borel spaces (a set that is both analytic and coanalytic is necessarily Borel), the inverse of any such measurable bijective function is also measurable.
