Construction of non-Hopfian groups as direct limits of relatively hyperbolic groups
In this paper, we construct a family of two types of finitely generated non-Hopfian groups with explicit presentations, where the first type satisfies small cancellation conditions [Formula: see text] and [Formula: see text], and interpret these groups as direct limits of relatively hyperbolic groups and ordinary hyperbolic groups, respectively.
