摘要
主要运用pell方程、递推序列、同余式及(非)平方剩余等一些初等方法,证明了不定方程x(x+1)(x+2)(x+3)=21y(y+1)(y+2)(y+3)和x(x+1)(x+2)(x+3)=23y(y+1)(y+2)(y+3)无正整数解.
With the elementary method of Pell equations,recurrence sequence,congruent form and quadratic residue,it is shown that the indefinite equation x( x+1)( x + 2)( x + 3) = 21y( y + 1)( y + 2)( y + 3) and x( x + 1)( x+2)( x+3) = 23y( y+1) ·( y+2)( y+3) has no positive solution.
