Factorization of the Baire equivalence through Baire envelopes

Determine whether the contravariant equivalence between Baire measurable spaces and commutative Pedersen–Baire envelopes (BaireMeas ≅ cPedBaireC) factors through the Baire envelope construction on Boolean algebras.

Background

The paper establishes a duality between Baire measurable spaces and commutative Pedersen–Baire envelope C*-algebras. Baire envelopes of Boolean algebras, however, correspond only to those Baire spaces arising from Stone spaces, so it is nontrivial whether the full equivalence passes through this intermediate construction.

References

Since Baire envelopes of Boolean algebras correspond only to those Baire measurable spaces arising from Stone spaces, it is not clear whether the equivalence $BaireMeas \cong cPedBaireC$ factors through Baire envelopes; we leave this open for future investigation.
