A Note on Ultrametric Spaces, Minimum Spanning Trees and the Topological Distance Algorithm

open access: yesInformation, 2020
We relate the definition of an ultrametric space to the topological distance algorithm—an algorithm defined in the context of peer-to-peer network applications.

Supereulerian Graphs and the Petersen Graph

open access: yesJournal of Combinatorial Theory, Series B, 1996
A graph \(G\) is called supereulerian if \(G\) has a spanning closed trail. Using a reduction technique, which was developed by the first author [A reduction method to find spanning Eulerian subgraphs, J. Graph Theory 12, No. 1, 29-45 (1988; Zbl 0659.05073)], the authors prove that any 3-edge-connected graph with at most 10 edge cuts of size 3 either ...

Independent sets of maximum weight in apple-free graphs [PDF]

open access: yes, 2010
We present the first polynomial-time algorithm to solve the maximum weight independent set problem for apple-free graphs, which is a common generalization of several important classes where the problem can be solved efficiently, such as claw-free graphs,

Graph equations for line graphs and total graphs

open access: yesDiscrete Mathematics, 1975
AbstractAll pairs (G,H) of graphs G,H satisfying L(G) = T(H) are determined. The “graph equation“ L(G)= T(H) is also solved.
