For instance, given simply connected algebraic \(K\)-groups \(G\) and \(H\) with Lie algebras \(\mathfrak{g}\) and \(\mathfrak{h}\), respectively, there may be a homomorphism of Lie algebras \(\mathfrak{g} \to \mathfrak{h}\) which \emph{does not} come from a rational -homomorphism \(G \to H\). +homomorphism \(G \to H\) -- see \cite[ch.~II]{demazure-gabriel} for instance. In other words, the Lie functor \(K\text{-}\mathbf{Grp}_{\operatorname{simpl}} \to K\text{-}\mathbf{LieAlg}\) fails to be full. Furthermore, there are
