摘要
We prove that in any compact symmetric space, G/K, there is a dense set of a(1), a(2) is an element of G Such that if mu(j) = m(K) * delta(aj) * m(k) is the K-bi-invariant measure supported on Ka(j)K, then mu(1) * mu(2) is absolutely continuous with respect to Haar measure on G. Moreover, the product of double cosets, Ka(1)Ka(2)K, has nonempty interior in G.
