On the structure of the Selberg class, IV: basic invariants
The (−β)-integers are natural generalisations of the β-integers, and thus of the integers, for negative real bases. When β is the analogue of a Parry number, we describe the structure of the set of (−β)-integers by a fixed point of an anti-morphism.
Let be the rational function field over a finite field of elements. For any polynomial with positive degree, denote by the torsion points of the Carlitz module for the polynomial ring . In this short paper, we will determine an explicit formula for the analytic class number for the unique subfield of the cyclotomic function field of degree over , where is an irreducible polynomial of positive degree and is a positive divisor of . A formula for the analytic class number for the...
Let b ≥ 2 be a fixed positive integer. We show for a wide variety of sequences {a n}n=1∞ that for almost all n the sum of digits of a n in base b is at least c b log n, where c b is a constant depending on b and on the sequence. Our approach covers several integer sequences arising from number theory and combinatorics.
We show that for any relatively prime integers 1 ≤ p < q and for any finite A ⊂ ℤ one has .
Let ϕ(n) be the Euler function of n. We put and give an asymptotic formula for the second moment of E(n).
It can be shown that the positive integers representable as the sum of two squares and one power of k (k any fixed integer ≥ 2) have positive density, from which it follows that those integers representable as the sum of two squares and (at most) two powers of k also have positive density. The purpose of this paper is to show that there is an infinity of positive integers not representable as the sum of two squares and two (or fewer) powers of k, k again any fixed integer ≥ 2.
