Noise as a Boolean algebra of $\sigma$-fields

Probability 2014-01-16 v3

Abstract

A noise is a kind of homomorphism from a Boolean algebra of domains to the lattice of σ\sigma-fields. Leaving aside the homomorphism we examine its image, a Boolean algebra of σ\sigma-fields. The largest extension of such Boolean algebra of σ\sigma-fields, being well-defined always, is a complete Boolean algebra if and only if the noise is classical, which answers an old question of J. Feldman.
