Let $K$ be an algebraically closed field of characteristic zero and $R$ an algebraic extension of the field of rational functions $K(x_1,.,x_n)$ in $n$ variables. We study centralizers of elements in the Lie algebra $Der_{K}R$ of all $K$-derivations of the field $R.$If $F$ is the field of constants...
