“…In [17], it has been proved that λ(K) = µ(K) = ν(K) = 0, i.e., L(K ∞ ) = K ∞ . (As in [17], we can see that #A(K 1 ) = 1 by Theorem 5.6 of [6]. By using Theorem 1 of [7], we get…”

“…with a fixed place oo of degree d. Let £(oo) be the residue field at oo. Fix a sign function (see [5] for definitions) sgn : K^ -* fc(oo) SunghanBae and Ja Kyung Koo [2] where AT^ is the completion of K at oo and a n uniformizer at oo with sgn(7r) = 1. In applications K x replaces K, so we need an analog of the field of complex numbers C. Define C = K^ ((-n) lKqd~X) ).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
