Additive Diophantine inequalities with mixed powers II
Published online by Cambridge University Press: 26 February 2010
Extract
A classical problem in the additive theory of numbers is the determination of the minimal s such that for all sufficiently large n the equation
is solvable in natural numbers xk. Improving on earlier results the author [2] has been able to prove that one may take s = 18. In a survey article W. Schwarz asked for an analogue for diophantine inequalities [6]. As a first contribution to this subject we prove
Theorem. Let λ2, …, λ23 be nonzero real numbers, λ2/λ3 irrational. Then the values taken by
at integer points ( x1, …, x22) are dense on the real line.
