Title: Regular graphs and ternary quadratic forms

Abstract: In this talk, we introduce some properties of the graph defined on the genus of a positive definite ternary quadratic forms. In particular, we give a necessary and sufficient condition for the above graph to be regular. Furthermore, we provide an effective procedure to construct a genus consisting of classes whose isometry groups are trivial.
