A Diophantine equation. (English) Zbl 0576.10010
The author finds by the elementary theory of algebraic number fields all the cases when the sum of three consecutive integral cubes is a square; that is to find all integral solutions \(x,y\) of \(y^ 2=(x-1)^ 3+x^ 3+(x+1)^ 3=3x(x^ 2+2)\).
Editor’s remark: In an addendum in Glasg. Math. J. 29, 275 (1987; Zbl 0642.10019) priority of this result for S. Uchiyama is acknowledged.
