Integral quadratic forms and graphs are both specified by symmetric matrices of integers. It is therefore reasonable to ask whether quadratic forms can tell us anything about graphs. We’ll explore this, with special attention to the graph isomorphism problem. The talk will be largely expository. In particular, no background in the theory of quadratic forms will be assumed.
