Abstract
We show that the graph isomorphism problem is equivalent to the problem of recognizing equal simplices in ℝn. This result can lead to new methods in the graph isomorphism problem based on geometrical properties of simplices. In particular, relations between several well-known classes of invariants of graphs and geometrical invariants of simplices are established.
