Noise as a Boolean algebra of -fields
arXiv:1111.7270 · doi:10.1214/13-AOP861
Abstract
A noise is a kind of homomorphism from a Boolean algebra of domains to the lattice of -fields. Leaving aside the homomorphism we examine its image, a Boolean algebra of -fields. The largest extension of such Boolean algebra of -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.
