摘要 本文将证明以下结论:设m为正整数,当(a,c,δ)取(m,m+1,-1),(m,m+ 2,-2),(m,m+4,-4),或者(m+2,m,2)时,联立的不定方程组■的正整数解(x,y,z)的个数不超过1。 In this paper, we prove that if m 〉 0 is an integer, and (α, c, δ) = (m, m + 1, -1), (m, m+2,-2), (m, m+4, -4), or (m+2, m, 2), then simultaneous Pell equations {αx^2-cy^2=δ,y^2-bz^2=1 possess at most one positive integer solution (x, y, z).
