Properly even harmonious labelings of disconnected graphs
A graph G with q edges is said to be harmonious if there is an injection f from the vertices of G to the group of integers modulo q such that when each edge xy is assigned the label f(x)+f(y)(modq), the resulting edge labels are distinct. If G is a tree,

Even harmonious labelings of disjoint graphs with a small component
A graph G with q edges is said to be harmonious if there is an injection f from the vertices of G to the group of integers modulo q such that when each edge xy is assigned the label f(x)+f(y)(modq), the resulting edge labels are distinct. If G is a tree,

THE HARMONIOUS, ODD HARMONIOUS, AND EVEN HARMONIOUS LABELING [PDF]
Suppose is a simple and connected graph with edges. A harmonious labeling on a graph is an injective function so that there exists a bijective function where for each An odd harmonious labeling on a graph is an injective function from to non-negative integer set less than so that there is a function where for every An even harmonious ...

Properly even harmonious labelings of complete tripartite graph K1,m,n and union of two coconut tree graphs [PDF]
Let G be a finite graph, without loops nor multiple edges, having q edges. A function f is called properly even harmonious labeling on G if f is an injection from V (G) to {0,1, 2, …,2q −1} and the induced function f* from E(H) to {0, 2, 4, …, 2q - 2}, with f*(xy) = (f(x) + f(y)) (mod 2q), is a bijective.

Harmonious Labelings Via Cosets and Subcosets [PDF]
In [Abueida, A. and Roblee, K., More harmonious labelings of families of disjoint unions of an odd cycle and certain trees, J. Combin. Math. Combin. Comput., 115 (2020), 61-68] it is shown that the disjoint union of an odd cycle and certain paths is ...

A PROPERLY EVEN HARMONIOUS LABELING OF SOME WHEEL GRAPH W_n FOR n IS EVEN [PDF]
A properly even harmonious labeling of a graph G with q edges is an injective mapping f from the vertices of graph G to the integers from 0 to 2q-1 such that induces a bijective mapping f* from the edges of G to {0,2,...,2q-2} defined by f*(v_iv_j)=(f(v_i)+f(v_j))(mod2q).

Harmonious graphs from α-trees
Two of the most studied graph labelings are the types of harmonious and graceful. A harmonious labeling of a graph of size m and order n, is an injective assignment of nonnegative integers smaller than m, such that the weights of the edges, which are ...

Even odd Harmonious Labeling of Some Graphs
Let G = be a graph, with and . An injective mapping is called an even-odd harmonious labeling of the graph G, if an induced edge mapping such that (i) is bijective mapping (ii) The graph acquired from this labeling is called even-odd harmonious graph. In this paper, we discovered some interesting results like H-graph, comb graph, bistar graph and graph
