A new proof of a theorem of Trofimov
Abstract: Let $\Gamma$ be a vertex symmetric, locally finite graph and endow $Aut(\Gamma)$ with the topology of pointwise
convergence. It is easy to see $B(G):=\{g\in Aut(\Gamma):\exists n \forall v\in V\Gamma d(v,gv)\leq n\}$ is a subgroup.
Trofimov proved that $B(G)$ is also closed. In this talk
a new, elementary proof is given of Trofimov's result.
