چکیده
A signed graph is a simple with two types of edges: positive and negative. homomorphism from G to another H mapping \(\varphi : V(G) \rightarrow V(H)\) that preserves vertex adjacencies balance closed walks (the the parity number negative edges). The chromatic \(\chi _s(G)\) order smallest such there H.

k-forested choosability of graphs with bounded maximum average degree
A proper vertex coloring of a simple graph is $k$-forested if the graph induced by the vertices of any two color classes is a forest with maximum degree less than $k$. A graph is $k$-forested $q$-choosable if for a given list of $q$ colors associated with each vertex $v$, there exists a $k$-forested coloring of $G$ such that each vertex receives a color from its own list. In this paper, we prov...

متن کاملGraphs with chromatic number close to maximum degree
Let G be a color-critical graph with χ(G) ≥ Δ(G) = 2t + 1 ≥ 5 such that the subgraph of G induced by the vertices of degree 2t+1 has clique number at most t−1. We prove that then either t ≥ 3 and G = K2t+2 or t = 2 and G ∈ {K6, O5}, where O5 is a special graph with χ(O5) = 5 and |O5| = 9. This result for t ≥ 3 improves a case of a theorem by Rabern [9] and for t = 2 answers a question raised by...
متن کاملThe locating-chromatic number for Halin graphs
Let G be a connected graph. Let f be a proper k -coloring of G and Π = (R_1, R_2, . . . , R_k) bean ordered partition of V (G) into color classes. For any vertex v of G, define the color code c_Π(v) of v with respect to Π to be a k -tuple (d(v, R_1), d(v, R_2), . . . , d(v, R_k)), where d(v, R_i) is the min{d(v, x)|x ∈ R_i}. If distinct vertices have distinct color codes, then we call f a locat...
