摘要
设D是6k+1型的奇素数,运用Pell方程px2-3y2=1的最小解、同余式、平方剩余等初等方法给出了:当D=12t2+1(t是奇数)时,Diophantine方程x3+1=Dy2无正整数解的一个充分条件.
Let D be an odd prime of the form 6k+l. Using the elementary method of the least solution of the Pell equation px^2-3y^2=l, congruent formula and quadratic residue, a sufficient condition is obtained that the exponential Diophantine equation x^3+l=Dy^2 has no integer solutions, where D=12t^2+I(t is an odd number).
