关于丢番图方程x~3±64=3Dy~2
On the Diophantine Equation x ̄3±64=3Dy ̄2
【摘要】 给出了方程x~3±64=3Dy~2无非平凡整数解的充分性条件。
【Abstract】 Theorem 1. If D>2,and d|D,d is not a square.d≠3.d is not prime of the from 6K+1 ,then when,38 (mod 40), the equation x ̄3±64=3Dy ̄2 have not nontrivial integral solution. Therem3. Suppose D=Ⅱpi.s≥2. pi≠pj(1≤i≠j≤s). are primes. if exist j,2≤j≤s satisfy =-1, then the equation x ̄3±64 =3Dy ̄2 have not nontrivial inteqral solution in the following: 1)p1= 13,19(mod24), pj≡5 (mod 6),j=2,…, s ; or 2) p1≡1 (mod6) ,pj≡11,17(mod 24), j=2,…,s; or 3) p1≡1 (mod6),pj≡5(mod 6) ,j=2,…,s(mod8).
