Abstract
We consider the diophant moment problem
where dμ(λ) is a positive measure and the nk’s are positive integers. The fact that the nk’s are integers puts stringent constraints on the measure dμ(λ). One of the simplest results we obtain is that for Λ < 4, dμ(λ) is a finite sum of Dirac measures. An infinite number of bifurcation points in the parameter A occur in this problem. They are located at the points 4 cos2 π/m, m = 2,3,4,… with an accumulation point at Λ = 4.
