| We give a topological framework for the study of Sela's limit groups:limit groups are limits of free groups in a compact space of markedgroups.Many results get a natural interpretation in this setting.The class of limit groups is known to coincide with the class offinitely generated fully residually free groups.The topological approach gives some new insight on the relation betweenfully residually free groups, the universal theory of free groups,ultraproducts and non-standard free groups. |
