Introduction to graceful graphs 2 rn r is a crown with 2n edges in such a way that each edge receives a distinct positive integer as an edge label (edge value or edge number) depending on the vertex labels of vertices which are.

Theorem 101 two graphs g1 and g2 are isomorphic if and only if their incidence ma- trices a(g 1 ) and a(g 2 ) differ onlyby permutationof rows and columns proof let the graphs g 1 and g 2 be isomorphic. Graph coloring homework book problems 1 prove that isomorphic graphs have the same chromatic number and the same chromatic poly-nomial let gand g0be isomorphic graphsthe, there is a function ˚: gg0such that ˚(u i) = v j. Graph theory “begin at the beginning,” the king said, gravely, “and go on till you in this section we will introduce a number of basic graph theory terms and and the size of a graph is the cardinality of its edge set given two vertices u and v, if uv ∈ e, then u and v are said to be adjacent in. For a graph, a function is called an edge product cordial labeling of g, if the induced vertex labeling function is defined by the product of the labels of the incident edges as such that the number of edges with label 1 and the number of edges with label 0 differ by at most 1 and the number of. The crown graph can be viewed as a complete bipartite graph from which the edges of a perfect matching have been removed, as the bipartite double cover of a complete graph , as the tensor product k n × k 2 , as the complement of the cartesian direct product of k n and k 2 , or as a bipartite kneser graph h n ,1 representing the 1-item and ( n.

Bound of distance domination number of graph and edge comb product graph aw gembong 1,2, slamin 1,3, dafik 1,4 and ika hesti agustin 1,2 published under licence by iop publishing ltd in addition, we determine the bound of distance domination number of edge comb product graph. 44 shortest paths shortest paths an edge-weighted digraph is a digraph where we associate weights or costs with each edge a shortest path from vertex s to vertex t is a directed path from s to t with the property that no other such path has a lower weight properties we summarize several important properties and assumptions. A graph g is said to be an edge product graph if there exists an edge function f: e → p such that the function f and its corresponding edge product function f on v satisfies that f(v) p for every v v and if e1, e2,,ep e such that f(e1) f(e2) f(ep) p then the edges e1, e2,,ep are incident on a vertex. Graph theory notes vadim lozin institute of mathematics university of warwick denoted deg(v), is the number of edges incident to v alternatively, deg(v) = jn(v)j if deg(v) = 0, then vertex vis called isolated we count each edge of the graph twice, because each edge is incident to exactly two vertices. You then remove any edge in the cycle, you get back a spanning tree (removing one edge from a cycle cannot disconnect a graph) theorem 142 prim’s algorithm correctly finds a minimum spanning tree of the given graph.

Cycle, product-relatedgraphs 1 introduction delorme [15] has shown that the union of nc4 having one edge in common and union of nf{4 having one edge in conution are graceful delorme et al, [16] call the resulting graph as double crown or double corona the graph so obtained is denoted by en 8 1(2. The edge geodetic number is investigated in cartesian product graphs in , where we observe that the edge geodetic number and the geodetic number have significant difference motivated by this work, in this paper, we study the edge geodetic number in other standard graph products, namely the strong products and lexico-graphic products.

2001, p63-75) the concept of graph labeling is a frontier between number theory and structure of graphs definition 12 a mapping f: v(g) →{0,1} triangular snakes, dragons, helms and union of two path graphs are product cordial they also proved that a graph with thus the edge condition for product cordial graph is violated hence. Intuitively speaking, an edge-magic graph is perfect edge-magic if all possible theoretical valences occur in particular, we prove that for each integer m 0, that is the power of an odd prime, and for each natural number n, the crown product c-m circle dot (k-n) over bar is perfect edge-magic. Product of the labels of the incident edges as such that the number of edges with label n by a new vertex in a crown graph is edge product cordial graph as shown in figure 4 figure 4 n =5 theorem 4 the graph obtained by duplication of each pendent vertex by a new.
