Resumen de The fields of real and complex numbers with a small multiplicative group

Lou van den Dries, Ayhan Günaydin

• We consider the model theory of the real and complex fields with a multiplicative group having the Mann property. Among these groups are the finitely generated multiplicative groups in these fields. As a by-product we obtain some results on groups with the Mann property in rings of Witt vectors and in fields of positive characteristic.k
