The edge-distinguishing chromatic number (EDCN) of a graph G is the minimum positive integer k such that there exists a vertex coloring c : V(G)?{1, 2, …, k} whose induced edge labels {c(u),c(v)} are distinct for al... see more

Let G and H be two given graphs. The notation F?(G,H) means that any red-blue coloring on the edges of F will create either a red subgraph G or a blue subgraph H in F. A graph F is a Ramsey (G,H)-minimal graph if F satisfies two conditions: (1) F?(G,H), a... see more

We use Rosa-type labelings to decompose complete graphs into unicyclic, disconnected, bipartite graphs on nine edges – namely, those featuring cyclic component C4, C6, or C8. For any such graph H, we prove there exists an H-design... see more

Let G = (V, E) be a simple undirected graph. A labeling f : V(G)?{1, …, k} is a local inclusive d-distance vertex irregular labeling of G if every adjacent vertices x, y ? V(G) have distinct weights, with the w... see more

In this paper, the vertex-degree function index Hf(G) is considered when function f(x) belongs to four classes of functions determined by the following properties: strictly convex versus strictly concave and strictly increasing versus ... see more

Let G = (V(G),E(G)) be a graph with the nonempty vertex set V(G) and the edge set E(G). Let Zn be the group of integers modulo n and let k be a positive integer. A modular irregular labeling of a grap... see more

Let G be a connected, simple, and undirrected graph, where V (G) is the vertex set and E(G) is the edge set. Let k be a natural numbers. For graph G we define a total k-labeling ? such that the vertices of graph G are labeled with {0, 2, 4, . . . , 2kv} a... see more

We study random subcube intersection graphs, that is, graphs obtained by selecting a random collection of subcubes of a fixed hypercube QdQ_d to serve as the vertices of the graph, and setting an edge between a pair of subcubes if their intersection is no... see more

This short note proves that every non-complete kk-list-critical graph has average degree at least k-1+k-3k2-2k+2k-1 + \frac{k-3}{k^2-2k+2}. This improves the best known bound for k=4,5,6k = 4,5,6. The same bound holds for online kk-list-critical graphs.
