Loi de répartition moyenne des diviseurs des entiers friables

Joseph Basquin (2014)

Journal de Théorie des Nombres de Bordeaux

In this paper we consider an extension to friable integers of the arcsine law for the mean distribution of the divisors of integers, originally due to Deshouillers, Dress and Tenenbaum.We describe the limit law and show that it departs from the arcsine law when the friability parameter u : = log x / log y increases. More precisely, as u , the mean distribution shifts from the arcsine law towards Gaussian behaviour.

Mean values connected with the Dedekind zeta-function of a non-normal cubic field

Guangshi Lü (2013)

Open Mathematics

After Landau’s famous work, many authors contributed to some mean values connected with the Dedekind zetafunction. In this paper, we are interested in the integral power sums of the coefficients of the Dedekind zeta function of a non-normal cubic extension K 3/ℚ, i.e. S l , K 3 ( x ) = m x M l ( m ) , where M(m) denotes the number of integral ideals of the field K 3 of norm m and l ∈ ℕ. We improve the previous results for S 2 , K 3 ( x ) and S 3 , K 3 ( x ) .

Multiplicative functions dictated by Artin symbols

Robert J. Lemke Oliver (2013)

Acta Arithmetica

Granville and Soundararajan have recently suggested that a general study of multiplicative functions could form the basis of analytic number theory without zeros of L-functions; this is the so-called pretentious view of analytic number theory. Here we study multiplicative functions which arise from the arithmetic of number fields. For each finite Galois extension K/ℚ, we construct a natural class K of completely multiplicative functions whose values are dictated by Artin symbols, and we show that...
