comment how to solve this symmetrical equation in number theory
It's linear in $m_1$ and you can force the coefficient of $m_1$ to be $1$ by a choice of $m_2,m_3$. That gives one solution. Do you just need a solution or all of them?

comment The sequence $a_{n+1}=\left\lceil \frac{-1+\sqrt{5}}{2}a_{n}-a_{n-1} \right\rceil$ is periodic
I still think this should not be on MO. It may be a hard problem but is not a research problem, i.e., I doubt it arose independently in jack's research. Second, I assume whoever posed the problem in the competition (plus, I hope, some of the competitors) know how to solve it, so asking them and not MO is a more efficient way of getting the answer.

comment The Sato-Tate conjecture (Frobenius eigenvalues)
When the elliptic curve has CM by a class number one ring then the eigenvalues of Frobenius are $\pm \sqrt{p}$ for the inert primes and $\pi,\bar{\pi}$ if $p$ factors as $\pi \bar{\pi}$ in the ring.
