On the Tamagawa number conjecture for newforms at Eisenstein primes

Number Theory 2025-09-12 v2

Abstract

We extend the results of [CGLS22] to higher weight modular forms and prove a rank 00 Tamagawa number formula (also known as the Bloch-Kato conjecture) for modular forms at good Eisenstein primes, under some technical assumption on periods. Under standard hypotheses (i.e. the injectivity of the pp-adic Abel-Jabobi map and the non-degeneracy of the Gillet-Soul\'e height pairing), we also discuss some partial results towards a rank 11 result. A conditional higher weight pp-converse theorem to Gross-Zagier-Zhang-Kolyvagin-Nekov\'a\v{r} is also obtained as a consequence of the anticyclotomic Iwasawa Main Conjectures.
