The authors generalize results of Mazur and Tilouine giving a proof of the anticyclotomic main conjecture. More precisely, they prove a generalization, to the \(CM\) case, of certain divisibility relations (predicted by the main conjecture) between a Katz \(p\)-adic \(L\)-function and certain characteristic power series. They also re-prove some of the divisibility results of Mazur-Tilouine without the additional hypotheses needed in the original proof. The proof uses the theory of deformations of Galois representations over finite extensions of \(\mathbb{Q}_ p\).
