The necessary and sufficient conditions
have been obtained for extendability of a Banach representation of a generating Lie semigroup to a local representation of the Lie group generated by when the tangent wedge of is a Lie semialgebra. The most convenient conditions we obtain correspond to the case of unitary representations. In this case, we give a
criterion of global extendability if is exponential and solvable.
