Aug 5, 2010 at 16:19 comment added Andreas Thom Right, under some conditions on the element $x$, Hille can show that the exponential map is open at $x$. His conditions are sufficient but probably not necessary. If the answer to the Question is negative, one should ask about a precise characterization of the elements where $\exp$ is open.
Aug 5, 2010 at 16:14 comment added Mariano Suárez-Álvarez You say that "Hille shows that the answer is positive" yet apparently the question is of the form "which elements...?".
