WebS U ( 2) is the “base case” of the recursion—we simply have the Haar measure as expressed above. Moving on up, we can write elements of S U ( 3) as a sequence of three S U ( 2) transformations. The Haar measure d μ 3 then consists of two copies of d μ 2, with an extra term in between to take into account the middle transformation.
