Beurling's generalized prime system is a sequence of real numbers satisfying . The multiplicative semigroup generated by is called a system of Beurling's generalized integers. If and denote the counting functions of generalized primes and of generalized integers , respectively, Beurling's problem is to find conditions on which imply "the prime number theorem", i.e., as . Assuming that , Beurling's condition is with ; but does not suffice. Bateman and Diamond conjectured the condition . A proof of this conjecture following Kahane's method is given in this paper. The proof is based on Poission's summation formula and the Wiener-Ikehara tauberian theorem and applies classical ideas.
