A strong edge-coloring of a graph $G$ is an edge-coloring in which every color class is an induced matching, and the strong chromatic index $\chi_s'(G)$ is the minimum number of colors needed in strong edge-colorings of $G$. A graph is $2$-degenerate

For a set of nonnegative integers c 1 , … , c k , a ( c 1 , c 2 , … , c k ) -coloring of a graph G is a partition of V ( G ) into V 1 , … , V k such that for every i , 1 ≤ i ≤ k , G [ V i ] has maximum degree at most c i . In this paper, we
An edge (vertex) cut $X$ of $G$ is $r$-essential if $G-X$ has two components each of which has at least $r$ edges. A graph $G$ is $r$-essentially $k$-edge-connected (resp. $k$-connected) if it has no $r$-essential edge (resp. vertex) cuts of size les

For a given graph $H$, a graph $G$ is H-linked if, for every injection $\varphi: V(H) \to V(G)$, the graph $G$ contains a subdivision of $H$ with $\varphi(v)$ corresponding to $v$ for each $v\in V(...
An odd coloring of a graph $G$ is a proper coloring such that any non-isolated vertex in $G$ has a coloring appears odd times on its neighbors. The odd chromatic number, denoted by $\chi_o(G)$, is the minimum number of colors that admits an odd color

A graph is near-bipartite if its vertex set can be partitioned into an independent set and a set that induces a forest. It is clear that near-bipartite graphs are 3-colorable. In this note, we show that planar graphs without cycles of lengths in { 4

For a sequence of non-decreasing positive integers S = ( s 1 , … , s k ) , a packing S -coloring is a partition of V ( G ) into sets V 1 , … , V k such that for each 1 ≤ i ≤ k the distance between any two distinct x , y ∈ V i is at least s
