On 2-Adic L-Functions and Cyclotomic Invariants.
Let be a prime, let . Let be the norm of under , so that is a purely ramified extension of discrete valuation rings of degree . The minimal polynomial of over is an Eisenstein polynomial; we give lower bounds for its coefficient valuations at . The function field analogue, as introduced by Carlitz and Hayes, is studied as well.
The aim of this paper is to prove the following Theorem Theorem Let be an octic subfield of the field and let be prime. Then divides if and only if divides for some , , , .
