Non-commutative $L$-functions for $p$-adic representations over totally real fields

25 Oct 2017  ·  Witte Malte ·

We prove a unicity result for the $L$-functions appearing in the non-commutative Iwasawa main conjecture over totally real fields. We then consider continuous representations $\rho$ of the absolute Galois group of a totally real field $F$ on adic rings in the sense of Fukaya and Kato... Using our unicity result, we show that there exists a unique sensible definition of a non-commutative $L$-function for any such $\rho$ that factors through the Galois group of a possibly infinite totally real extension. We also consider the case of CM-extensions and discuss the relation with the equivariant main conjecture for realisations of abstract $1$-motives of Greither and Popescu. read more
