će održati predavanje pod naslovom:
WHERE GROUPS = GRAPHS = TOPOLOGY
 

 Sažetak:

A group is non-Hopfian if it has proper quotients which are isomorphic to itself.  The Baumslag-Solitar groups [Baumslag, G., Solitar, D., 1962] were the first known examples of 2 generator, 1 relator non-Hopfian groups.  They, and the broader class of generalized Baumslag-Solitar (GBS) groups, have since become test beds for various sorts of conjectures in group theory. The class of GBS groups is intimately connected to a class of graphs, the GBS graphs, and a class of topological spaces, the GBS complexes.  We explore those connections and, we hope, provide a justification for the title chosen for this talk.
