运用同余式、平方剩余和勒让德符号的性质等得出了不定方程x^3±53=3Dy^2无正整数解的2个充分条件,从而推进了该类不定方程的研究.
Congruence, quadratic residue and some properties of Legendre were used to obtain two sufficient conditions of the indefinite equation x^3±53=3Dy^2 which have no integer solutions, which promote the research of this kind of indefinite equation.
