Abstract: | A theorem is proven which gives five characterizations of a multidimensional Bernoulli shift. The two-point extensions of
a multidimensional Bernoulli shift are classified completely. If such an extension is weakly mixing then it must be Bernoulli;
otherwise, it is isomorphic to one of 2
n
specific trivial extensions. This result is extended to multidimensional Bernoulli flows and Bernoulli shifts of infinite
entropy.
