The Hooley-Huxley contour method for problems in number fields III : frobenian functions

Mark D. Coleman (2001)

Journal de théorie des nombres de Bordeaux

In this paper we study finite valued multiplicative functions defined on ideals of a number field and whose values on the prime ideals depend only on the Frobenius class of the primes in some Galois extension. In particular we give asymptotic results when the ideals are restricted to “small regions”. Special cases concern Ramanujan's tau function in small intervals and relative norms in “small regions” of elements from a full module of the Galois extension.

The hyperbola x y = N

Javier Cilleruelo, Jorge Jiménez-Urroz (2000)

Journal de théorie des nombres de Bordeaux

We include several results providing bounds for an interval on the hyperbola x y = N containing k lattice points.

The joint distribution of Q -additive functions on polynomials over finite fields

Michael Drmota, Georg Gutenbrunner (2005)

Journal de Théorie des Nombres de Bordeaux

Let K be a finite field and Q K [ T ] a polynomial of positive degree. A function f on K [ T ] is called (completely) Q -additive if f ( A + B Q ) = f ( A ) + f ( B ) , where A , B K [ T ] and deg ( A ) < deg ( Q ) . We prove that the values ( f 1 ( A ) , ... , f d ( A ) ) are asymptotically equidistributed on the (finite) image set { ( f 1 ( A ) , ... , f d ...

The largest prime factor of X³ + 2

A. J. Irving (2015)

Acta Arithmetica

Improving on a theorem of Heath-Brown, we show that if X is sufficiently large then a positive proportion of the values n³ + 2: n ∈ (X,2X] have a prime factor larger than X 1 + 10 - 52 .
