comment Minimal polynomial of eigenvector entries
In fact I would be happy knowing just an upper bound on the height of v_i, that is the maximum of the absolute value of the coefficients of the minimal polynomial of v_i.

comment Minimal polynomial of eigenvector entries
I did know that, but I really need an explicit polynomial of which v_i is a root.

comment Determine direction of eigenvector
But computing the eigenvectors of $A$ requires finding the roots of the characteristic polynomial, and there is no closed expression for the roots of high degree polynomials.

comment Determine direction of eigenvector
A vector $v$ is non-negative if each entry of $v$ is non-negative, this is written $v \geq 0$.
