Ulam Numbers of Graphs,.. = {.., .., …, ..} of .., having the properties for all 1 ≤ . ≤ ., (1) |..| = |..| and (2) the subgraph .[..] induced by .. is isomorphic to the subgraph .[..] induced by ... In this note we generalize this concept, first introduced in 1979 by Chung et al. in Congr Numer 23:3–18, 1979.

Some of My Favourite Conjectures: Local Conditions Implying Global Cycle Properties,century. The town was spanned by seven bridges passing over the river Pregel and connecting the four land masses on which Königsberg was built. The townsfolk amused themselves by taking walks through Königsberg, attempting to cross each of the seven bridges exactly once. In 1736 Euler put an end to

The Path Partition Conjecture,. vertices, then there exists a partition (., .) of the vertex set of . such that . has no path with more than . vertices, and . has no path with more than . vertices. We present a brief history of the PPC, discuss its relation to other conjectures and examine results supporting the PPC that have ap

My Favorite Domination Game Conjectures, Staller, with conflicting goals collaboratively produce a dominating set in an underlying host graph. The players take turns choosing a vertex from the graph, where each vertex chosen must dominate at least one vertex not dominated by the set of vertices previously chosen. The game ends when there

,A De Bruijn-Erdős Theorem in Graphs?,ther the same statement holds true in general metric spaces, where the line determined by points . and . is defined as the set consisting of ., ., and all points . such that one of the three points ., ., . lies between the other two. The conjecture that it does hold true remains unresolved even in t
