Pell Equations: Non-Principal Lagrange Criteria and Central Norms
We provide a criterion for the central norm to be any value in the simple continued fraction expansion of √ D for any non-square integer D > 1. We also provide a simple criterion for the solvability of the Pell equation x2 − Dy2 = −1 in terms of congruence conditions modulo D.

We consider the Diophantine equation of the form x2−Dy2 = c, where c ∣∣ 2D, gcd(x, y) = 1, and provide criteria for solutions in terms of congruence conditions on the fundamental solution of the Pell Equation x2 − Dy2 = 1. The proofs are elementary, using only basic properties of simple continued fractions. The results generalize various criteria for such solutions, and expose the central norm,...

Suppose that p is an odd prime and d is a positive integer. Let x and y be integers given by p = x2 + dy2 or 4p = x2 + dy2. In this paper we determine x (mod p) for many values of d. For example,
متن کاملPell ’ s Equation
An arbitrary quadratic diophantine equation with two unknowns can be reduced to a Pell-type equation. How can such equations be solved? Recall that the general solution of a linear diophantine equation is a linear function of some parameters. This does not happen with general quadratic diophantine equations. However, as we will see later, in the case of such equations with two unknowns there st...
