If Lis a nitely rami ed extension of Qpthen the limit limz!1 z2L Lin(z) exists for n 2, and is independent of L. Using this limit as the value for Lin at 1, Lin extends to a function on Cp, which is continuous on nitely rami ed extensions of Qp. If mand nare integers at least equal to 2, then on Cp
