Xian-Jin Li gave a criterion for the Riemann hypothesis in terms of the positivity of a set of coefficients
Let be a finite extension of . The field of norms of a -adic Lie extension is a local field of characteristic which comes equipped with an action of . When can we lift this action to characteristic , along with a compatible Frobenius map? In this note, we formulate precisely this question, explain its relevance to the theory of -modules, and give a condition for the existence of certain types of lifts.
We give a self-contained exposition of local class field theory, via Lubin-Tate theory and the Hasse-Arf theorem, refining the arguments of Iwasawa [9].
Let be a rational prime and a complete discrete valuation field with residue field of positive characteristic . When is finite, generalizing the theory of Deligne [1], we construct in [10] and [11] a theory of local -constants for representations, over a complete local ring with an algebraically closed residue field of characteristic , of the Weil group of . In this paper, we generalize the results in [10] and [11] to the case where is an arbitrary perfect field.
The -adic local Langlands correspondence for attaches to any -dimensional irreducible -adic representation of an admissible unitary representation of . The unitary principal series of are those corresponding to trianguline representations. In this article, for , using the machinery of Colmez, we determine the space of locally analytic vectors for all non-exceptional unitary principal series of by proving a conjecture of Emerton.
