Vol. 213, nº 5 (2009), p. 1-140022-4049http://hdl.handle.net/10400.2/2910In this paper we prove, without assuming Schanuel's conjecture, that the E-subring generated by a real number not definable without parameters in the real exponential field is freely generated. We also obtain a similar result for the complex exponential field.engExponential reingsjournal article
