Let O denote the ring of integers of a local field. In this note we prove an ร 4 ฯฑ approximation theorem for the Riesz type kernels โฅ over O. The proof , , n ns1 ลฝ . y1 requires a sharp estimate of the Dirichlet kernel D x on P \_ O, which may also n have independent interest. As a consequence we so
Let p be a fixed odd prime number and k an imaginary abelian field containing a primitive p th root `p of unity. Let k รk be the cyclotomic Z p -extension and Lรk the maximal unramified pro-p abelian extension. We put where E is the group of units of k . Let X=Gal(Lรk ) and Y=Gal(L & Nรk ), and let
