Using Jiang function we prove Jiang prime k -tuple theorem. We prove that the Hardy-Littlewood prime k -tuple conjecture is false. Jiang prime k -tuple theorem can replace the Hardy-Littlewood prime k -tuple conjecture. (A) Jiang prime k -tuple theorem [1, 2]. We define the prime k -tuple equation , i p p n + , (1) where 2 , 1, 1 i n i k = β L . we have Jiang function [1, 2] 2 ( ) ( 1 ( )) P J P P Ο Ο = Ξ β β , (2) where P P Ο = Ξ , ( ) P Ο is the number of solutions of congruence
