On the diophantine equation (x^2+1)(y^2+1)=(z^2+1)^2 70194777 片山, 真一 カタヤマ, シンイチ Katayama, Shin-ichi 片山 カタヤマ Katayama 真一 シンイチ Shin-ichi open access In their paper [4]，A. Schinzel and W. Sierpinski have investigated the diophantine equaion (x^2- 1)(y^2-1)=(z^2-1)^2. In this paper，we shall investigate an analogous equation (x^2+1)(y^2+1)=(z^2+1)^2. 2006 eng departmental bulletin paper VoR 148377 https://tokushima-u.repo.nii.ac.jp/records/2001094 13467387 AA11595324 Journal of mathematics, the University of Tokushima 40 9 14 https://tokushima-u.repo.nii.ac.jp/record/2001094/files/LID201201312001.pdf application/pdf 318 KB 2012-01-31
