چکیده
|
In this paper, by reviewing the concept of regular and h−regular covering of graphs, we extendproperties of regular covering of graph to properties of h−regular covering of graph. for example, bydefinition of covh;ge0(g=g e ), we obtain covh;ge0(g=g e ) ∼ = h=p∗π1(g; e ge), where p : ge ! g is an h−regularcovering of graph and h ≤ π1(g; g0).
