$delta^(k)$-colouring of cycle related graphs
Johan Kok,N.K. Sudev 장전수학회 2022 Advanced Studies in Contemporary Mathematics Vol.32 No.1
With respect to a proper colouring of a graph G, we know that 2≤χ(G)≤∆(G)+1. If distinct colours represent distinct technology types to be located at vertices, the question arises on how to place at least one of each of k, 1≤k<χ(G), technology types together with the minimum adjacency between similar technology types. In an improper colouring, an edge uv such that c(u) = c(v) is called a bad edge. In this paper, we introduce the notion of δ(k)-colouring which is a near proper colouring of G with exactly 1≤k < χ(G) distinct colours which minimizes the number of bad edges.

Local treatment for hepatocellular carcinoma (HCC) has been widely used in clinical practice due to its minimal invasiveness and high rate of cure. Percutaneous radiofrequency ablation (RFA) is widely used because its treatment effectiveness. However, some serious complications can arise from percutaneous RFA. We present here a rare case of hemorrhagic cardiac tamponade secondary to an anterior cardiac vein (right marginal vein) injury during RFA for treatment of HCC.
