comment Does anyone know when the following definition was formulated.
Feit and Mollin proved this using Algebraic Number Fields. Robertson and Matthews proved in using Continued Fractions. Walsh generalized the result. Mollin has since given a major generalization.

Bill, Why do you think that the fact that $X^2-PY^2=a$, $P=a^2+(2b)^2$ an odd prime, has integer solutions did not get proved until 2000? It seems that it should have been proved much earlier, considering the proof given by Robertson/Matthews using continued fractions in 2005?

Thanks, that helps a lot!

comment Prove that $\mathbb{Z}_p^{\times}/(\mathbb{Z}_p^{\times})^2$ is isomorphic to $\{\pm1\}$.
What does $(\mathbb{Z}_p^x)^2$ mean. I was taking it to mean the cross product of $(\mathbb{Z}_p^x)$. Perhaps this is the confusion.
