Random algebra

In set theory, the random algebra or random real algebra is the Boolean algebra of measurable sets of the unit interval modulo the ideal of measure zero sets. It is used in random forcing to add random reals to a model of set theory. It was studied by von Neumann in 1935, in work later published as von Neumann (1998, p. 253).
