Computability of probability measures and Martin-Lof randomness over metric spaces
Given two reals x, z ∈ 2ω , x is called µ-random relative to z if no pµ -Martin-L¨of test {Un} uniformly enumerable in pµ ⊕ z covers x. A high useful fact about Martin-L¨of randomness is the existence of a universal test. A pµ -test (Un ) is universal if it covers every real that is covered by some pµ -test.
