The Pell Equation x2 − Py2 = Q

Authors: Ahmet Tekcan, Arzu Özkoç, Canan Kocapınar, Hatice Alkan


Let p be a prime number such that p ≡ 1(mod 4), say p = 1+4k for a positive integer k. Let P = 2k + 1 and Q = k2. In this paper, we consider the integer solutions of the Pell equation x2-Py2 = Q over Z and also over finite fields Fp. Also we deduce some relations on the integer solutions (xn, yn) of it.

Keywords: Pell equation, solutions of Pell equation.
