arXiv:2510.01601

Abstract

Let be a normalized newform of weight which is good at . Let be an imaginary quadratic field of class number one in which every prime divisor of splits. Let be an anticyclotomic Hecke character of which is crystalline at the primes above and such that . We prove that the Tamagawa number conjecture for the critical value follows from the Iwasawa main conjecture for the Bertolini-Darmon-Prasanna -adic -function.
