Euler Characteristics and their Congruences in the Positive Rank Setting

16 Apr 2020 Ray Anwesh Sujatha Ramdorai

The notion of the truncated Euler characteristic for Iwasawa modules is an extension of the notion of the usual Euler characteristic to the case when the homology groups are not finite. This article explores congruence relations between the truncated Euler characteristics for dual Selmer groups of elliptic curves with isomorphic residual representations, over admissible $p$-adic Lie extensions...
