AVDTC numbers of generalized Halin graphs with maximum degree at least 6

AVDTC numbers of generalized Halin graphs with maximum degree at least 6 In a paper by Zhang and Chen et al.(see [11]), a conjecture was made concerning the minimum number of colors χ at (G) required in a proper total-coloring of G so that any two adjacent vertices have different color sets, where the color set of a vertex ν is the set composed of the color of ν and the colors incident to ν. We find the exact values of χ at (G) and thus verify the conjecture when G is a Generalized Halin graph with maximum degree at least 6. A generalized Halin graph is a 2-connected plane graph G such that removing all the edges of the boundary of the exterior face of G (the degrees of the vertices in the boundary of exterior face of G are all three) gives a tree. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Mathematicae Applicatae Sinica Springer Journals

Abstract

In a paper by Zhang and Chen et al.(see [11]), a conjecture was made concerning the minimum number of colors χ at (G) required in a proper total-coloring of G so that any two adjacent vertices have different color sets, where the color set of a vertex ν is the set composed of the color of ν and the colors incident to ν. We find the exact values of χ at (G) and thus verify the conjecture when G is a Generalized Halin graph with maximum degree at least 6. A generalized Halin graph is a 2-connected plane graph G such that removing all the edges of the boundary of the exterior face of G (the degrees of the vertices in the boundary of exterior face of G are all three) gives a tree.
