چکیده

E. Bombieri and U. Zannier, motivated also by the above result, asked (private communication to the first author) for an absolute lower bound for the height of non-zero algebraic numbers lying in a complex abelian extension outside the set of roots of unity. This question was solved by R. Dvornicich and the first author (see [AmoDvo 2000]), who proved that for any α in a complex abelian extension, α 6= 0 and α not a root of unity, we have

On Hilbert Golab-Schinzel type functional equation

Let $X$ be a vector space over a field $K$ of real or complex numbers. We will prove the superstability of the following Go{l}c{a}b-Schinzel type equation$$f(x+g(x)y)=f(x)f(y), x,yin X,$$where $f,g:Xrightarrow K$ are unknown functions (satisfying some assumptions). Then we generalize the superstability result for this equation with values in the field of complex numbers to the case of an arbitr...

Orthogonal Decomposition of the Space of Algebraic Numbers and Lehmer’s Problem

Building on work of Dubickas and Smyth regarding the metric Mahler measure and the authors regarding extremal norms associated to the Mahler measure, the authors introduce a new set of norms associated to the Mahler measure of algebraic numbers which allow for an equivalent reformulation of problems like the Lehmer problem and the Schinzel-Zassenhaus conjecture on a single spectrum. We present ...

On a Transfer Theorem for the P 6= Np Conjecture

A model of computation is defined over the algebraic numbers and over number fields. This model is non-uniform, and the cost of operations depends on the height of the operands and on the degree of the extension of the rational defined by those operands. A transfer theorem for the P 6 = NP Conjecture is proved, namely: P 6 = NP in this model over the real algebraic numbers if and only if P 6 = ...

A Residue Scalar Product for Algebraic Function Fields over a Number Field

In 1953 Peter Roquette gave an arithmetic proof of the Riemann hypothesis for algebraic function fields over a finite constants field, which was proved by André Weil in 1940. The construction of Weil’s scalar product is essential in Roquette’s theory. In this paper a scalar product for algebraic function fields over a number field is constructed which is the analogue of Weil’s scalar product.

BULLETIN (New Series) OF THE AMERICAN MATHEMATICAL SOCIETY

The year 1948 saw the publication of Andre Weil’s monograph Sur les Courves Algebriques et les Variétés qui s’en Deduisent and of Claude Shannon’s work on The mathematical theory of communication. The first gave the details of Weil’s celebrated proof of the Riemann Hypothesis for algebraic curves over finite fields, while the second lay down the foundations for information theory, including the...
