On the diophantine equation (x^2+1)(y^2+1)=(z^2+1)^2 片山, 真一 1028 カタヤマ, シンイチ 60466/profile-ja.html Katayama, Shin-ichi 70194777 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. departmental bulletin paper 2006 VoR application/pdf Journal of mathematics, the University of Tokushima 40 9 14 13467387 AA11595324 https://tokushima-u.repo.nii.ac.jp/record/2001094/files/LID201201312001.pdf https://tokushima-u.repo.nii.ac.jp/records/2001094 eng
