摘要
On a Borel bar space (E, B,-), the following concepts are introduced in a suitable way: measurable fields of real Hilbert spaces, real measurable fields of vectors, operators and Von Neumann (VN) algebras: ξ(·),a(·),M(·) . Then a satisfactory real reduction theory is obtained: a real VN algebra M can be represented as a direct integral M=∫ (E,-) M(t) d ν(t), where each VN algebra M(t) in this field will be simpler.
