An elliptic curve having large integral points

Yanfeng He, Wenpeng Zhang (2010)

Czechoslovak Mathematical Journal

The main purpose of this paper is to prove that the elliptic curve E : y 2 = x 3 + 27 x - 62 has only the integral points ( x , y ) = ( 2 , 0 ) and ( 28844402 , ± 154914585540 ) , using elementary number theory methods and some known results on quadratic and quartic Diophantine equations.

An identity Ramanujan probably missed

Susil Kumar Jena (2015)

Colloquium Mathematicae

"Ramanujan's 6-10-8 identity" inspired Hirschhorn to formulate his "3-7-5 identity". Now, we give a new "6-14-10 identity" which we suppose Ramanujan would have discovered but missed to mention in his notebooks.
