Let \(\mathbb K\) be an arbitrary  field of characteristic zero and \(A\)  an integral \(\mathbb K\)-domain. Denote by \(R\) the fraction field of \(A\) and by \(W(A)=RDer_{\mathbb K}A,\) the Lie algebra of  \(\mathbb K\)-derivations on \(R\) obtained from \(Der_{\mathbb K}A\) via multiplication by...
