Solution to a Problem of Lubelski and an Improvement of a Theorem of His

A. Schinzel (2011)

Bulletin of the Polish Academy of Sciences. Mathematics

The paper consists of two parts, both related to problems of Lubelski, but unrelated otherwise. Theorem 1 enumerates for a = 1,2 the finitely many positive integers D such that every odd positive integer L that divides x² +Dy² for (x,y) = 1 has the property that either L or 2 a L is properly represented by x²+Dy². Theorem 2 asserts the following property of finite extensions k of ℚ : if a polynomial f ∈ k[x] for almost all prime ideals of k has modulo at least v linear factors, counting multiplicities,...

Some applications of decomposable form equations to resultant equations

K. Győry (1993)

Colloquium Mathematicae

1. Introduction. The purpose of this paper is to establish some general finiteness results (cf. Theorems 1 and 2) for resultant equations over an arbitrary finitely generated integral domain R over ℤ. Our Theorems 1 and 2 improve and generalize some results of Wirsing [25], Fujiwara [6], Schmidt [21] and Schlickewei [17] concerning resultant equations over ℤ. Theorems 1 and 2 are consequences of a finiteness result (cf. Theorem 3) on decomposable form equations over R. Some applications of Theorems...

Special values of multiple gamma functions

William Duke, Özlem Imamoḡlu (2006)

Journal de Théorie des Nombres de Bordeaux

We give a Chowla-Selberg type formula that connects a generalization of the eta-function to GL ( n ) with multiple gamma functions. We also present some simple infinite product identities for certain special values of the multiple gamma function.
