Abstract

Let ff be a newform of even weight at least 44, level NN and trivial character. Let pNp\nmid N be an odd prime number that is ordinary for ff and let KK be an imaginary quadratic field satisfying a generalized Heegner hypothesis relative to NN. In this paper, we prove (under mild arithmetic assumptions) Iwasawa main conjectures for ff over the anticyclotomic Zp\mathbb Z_p-extension of KK both in the definite setting and in the indefinite setting (in the second case, we prove a main conjecture \`a la Perrin-Riou for modular forms). Our strategy of proof follows the approach of Bertolini-Darmon via congruences combined with our previous results on an analogue for ff of Kolyvagin's conjecture on the non-triviality of his pp-adic system of derived Heegner points on elliptic curves. As a second contribution, when pp splits in KK we prove an Iwasawa-Greenberg main conjecture for the pp-adic LL-functions of Bertolini-Darmon-Prasanna and Brooks.
