This paper deals with the isomorphism problem of directed path graphs and rooted directed path graphs. Both graph classes belong to the class of chordal graphs, and for both classes the relative complexity of the isomorphism problem is yet unknown. We prove that deciding isomorphism of directed path

β¦ Synopsis
In this note we point out a flaw in the separator theorem for rooted directed vertex graphs due to C. L. Monma and V. K. Wei (1986, J. Combin. Theory Ser. B 41, 141 181), and present a modified separator theorem for the same class of graphs.

## Abstract We examine some properties of the 2βvariable greedoid polynomial __f__(__GΒ·,t,z__) when __G__ is the branching greedoid associated to a rooted graph or a rooted directed graph. For rooted digraphs, we show a factoring property of __f__(__GΒ·,t,z__) determines whether or not the rooted di
Combining two concepts of regularity of graphs, namely k-isoregularity and the t-vertex condition, a generalization of a classical result by Hestenes and Higman is presented. As an application it is shown that two infinite series of graphs constructed by Brouwer, Ivanov, and Klin which are not rank
