چکیده

Nathanson constructed bases of integers with a prescribed representation function, then asked how dense they can be. Chen constructed unique representation bases of integers which is infinitely often dense. In this paper, we will see how to construct bases of integers with a prescribed representation function which is infinitely often dense.

Infinitely Often Dense Bases for the Integers with a Prescribed Representation Function

Nathanson constructed asymptotic bases for the integers with prescribed representation functions, then asked how dense they can be. We can easily obtain an upper bound using a simple argument. In this paper, we will see this is indeed the best bound when we prescribe an arbitrary representation function.

Dense sets of integers with prescribed representation functions

Let A be a set of integers and let h ≥ 2. For every integer n, let rA,h(n) denote the number of representations of n in the form n = a1 + · · ·+ah, where ai ∈ A for 1 ≤ i ≤ h, and a1 ≤ · · · ≤ ah. The function rA,h : Z→ N, where N = N∪{0,∞}, is the representation function of order h for A. We prove that every function f : Z → N satisfying lim inf|n|→∞ f(n) ≥ g is the representation function of ...

On the Diophantine Equation x^6+ky^3=z^6+kw^3

Given the positive integers m,n, solving the well known symmetric Diophantine equation xm+kyn=zm+kwn, where k is a rational number, is a challenge. By computer calculations, we show that for all integers k from 1 to 500, the Diophantine equation x6+ky3=z6+kw3 has infinitely many nontrivial (y≠w) rational solutions. Clearly, the same result holds for positive integers k whose cube-free part is n...

A problem on unique representation bases

In this paper we construct a unique representation basis whose growth is more than x1/2−ε for infinitely many positive integers x , which solves a problem posed by Nathanson in [M.B.

MSC: 11B13; 11B34; 11B05 Let A be a set of integers, and let rA(n) = #{(a, b) : a, b...

Representation Functions of Bases for Binary Linear Forms

Let F (x1, . . . , xm) = u1x1 + · · · + umxm be a linear form with relatively prime integer coefficients u1, . . . , um. For any set A of integers, let F (A) = {F (a1, . . . , am) : ai ∈ A for i = 1, . . . , m}. The representation function associated with the form F is RA,F (n) = card ({(a1, . . . , am) ∈ A m : F (a1, . . . , am) = n}) . The set A is an asymptotic basis with respect to F if RA,...
