Sažetak

A perfect polynomial over the field $\F_4$ is a monic polynomial $A
\in \F_4[x]$ that equals the sum of all its monic divisors. If
$\gcd(A,x^4+x)=1$, then we say that $A$ is odd over $\F_4$. In this
paper, we characterize odd perfect polynomials over $\F_4$, with
four prime divisors. There follows a classification of all perfect
polynomials over $\F_4$ with up to four prime divisors.
