Zeta Functions of Graph Coverings
Graphs and digraphs treated here are finite and simple. Let G be a connected graph and D the symmetric digraph corresponding to G. A path P of length n in D(G) is a sequence P=(v0 , v1 , ..., vn&1 , vn) of n+1 vertices and n arcs (edges) such that consecutive vertices share an arc (edge) (we do not require that all vertices are distinct). Also, P is called a (v0 , vn)-path. The subdigraph (subg...
متن کاملWeighted Zeta Functions of Graph Coverings
We present a decomposition formula for the weighted zeta function of an irregular covering of a graph by its weighted L-functions. Moreover, we give a factorization of the weighted zeta function of an (irregular or regular) covering of a graph by equivalence classes of prime, reduced cycles of the base graph. As an application, we discuss the structure of balanced coverings of signed graphs.
متن کاملSome graph properties determined by edge zeta functions
Stark and Terras introduced the edge zeta function of a finite graph in 1996. The edge zeta function is the reciprocal of a polynomial in twice as many variables as edges in the graph and can be computed in polynomial time. We look at graph properties which we can determine using the edge zeta function. In particular, the edge zeta function is enough to deduce the clique number, the number of H...
متن کاملIsomorphisms of some graph coverings
Let G be a connected graph and r a group of automorphisms of G. We enumerate the number of r-isomorphism classes of derived graph coverings of G with voltages in a finite field of prime order P (>2).

The geometric-arithmetic index is another topological index was defined as 2 deg ( )deg ( ) ( ) deg ( ) deg ( ) G G uv E G G u v GA G u v , in which degree of vertex u denoted by degG (u). We now define a new version of GA index as 4 ( ) 2 ε ( )ε ( ) ( ) ε ( ) ε ( ) G G e uv E G G G u v GA G u v , where εG(u) is the eccentricity of vertex u. In this paper we compute this new t...
