Anticyclotomic Euler Systems for CM fields

Number Theory 2025-08-11 v1

Abstract

Let K/FK/F be a CM extension satisfying the ordinary assumption for an odd prime pp and let ψ\psi be a finite order anticyclotomic Hecke character of KK. When KK has a place above pp of degree one, we apply Urban's method and the results from our previous work to construct an anticyclotomic Euler system for ψ\psi under minor assumptions and prove one side o the divisibility of the anticyclotomic Iwasawa main conjecture for ψ\psi when pp is inverted.
