Abstract:
In our earlier work we exhibited a finitely presented group $G$ that we claimed enjoyed a geometric property called unbounded dead-end depth. We described a model for understanding the word metric on $G$, which regrettably was incorrect. Here, we describe the corrected model and the revised proof that $G$ does indeed have this property.References
