摘要 应用Bilu,Hanrot和Voutier关于本原素因子的深刻理论及二次数域类数的一些结果证明了丢番图方程(8a3-3a)2x+(3a2-1)y=(4a2-1)z仅有正整数解(x,y,z)=(1,1,3). Let a 〉 3 be an integer, the author applies a deep theorem of Bilu, Hanrot and Voutier and some resuits on the class number of quadratic field to show that the only positive integer solution of the diophantine equation (8a^3 -3a )^2x + (3a^2- 1)^y = (4a^2- 1)^z is (x,y,z)=(1,2,3).
