On Sums of Powers of Almost Equal Primes
We investigate the Waring-Goldbach problem of representing a positive integer n as the sum of s kth powers of almost equal prime numbers. Define sk = 2k(k − 1) when k > 3, and put s2 = 6. In addition, put θ2 = 19 24 , θ3 = 4 5 and θk = 5 6 (k > 4). Suppose that n satisfies the necessary congruence conditions, and put X = (n/s). We show that whenever s > sk and ε > 0, and n is sufficiently large...
متن کاملOn equal sums of ninth powers
In this paper, we develop an elementary method to obtain infinitely many solutions of the Diophantine equation x1 + x 9 2 + x 9 3 + x 9 4 + x 9 5 + x 9 6 = y 9 1 + y 9 2 + y 9 3 + y 9 4 + y 9 5 + y 9 6 and we give some numerical results.
متن کاملEqual sums of four seventh powers
In this paper, the method used to find the smallest, nontrivial, positive integer solution of a1 + a 7 2 + a 7 3 + a 7 4 = b 7 1 + b 7 2 + b 7 3 + b 7 4 is discussed. The solution is 149 + 123 + 14 + 10 = 146 + 129 + 90 + 15. Factors enabling this discovery are advances in computing power, available workstation memory, and the appropriate choice of optimized algorithms. Introduction Diophantine...
متن کاملSimultaneous equal sums of three powers
Using a result of Salberger [9] we show that the number of non-trivial positive integer solutions x0, . . . , x5 6 B to the simultaneous equations x0 + x c 1 + x c 2 = x c 3 + x c 4 + x c 5, x d 0 + x d 1 + x d 2 = x d 3 + x d 4 + x d 5, is o(B) whenever d > max{2, c}.
