Motivated by questions in Ramsey theory, we consider colorings of the edges of the complete graph Kn that contain no rainbow path Pt+1 of length t. If fewer than t colors are used then certainly there is no rainbow Pt+1. We show that, if at least t colors are used, then very few...
We want to derive a linear in (n−k) bound on the number of edges in a graph that does not contain (k+1)-connected subgraphs. But the bound becomes linear only for graphs with large number of vertices; while for small graphs the dependency is quadratic in n−k. The main difficult...

Finally, in Section 6, we prove our main theorem. 2. Signed graphs, re-signing, and odd minors A signed graph is a pair consisting of a graph together with a signature . The edges in are negative and the other edges are positive. A cycle (or path) is balanced if it contains an ...

Graph databases.Graph data stores organize data as nodes, which are similar to rows in a relational database, and edges, which represent connections between nodes. Because the graph system stores the relationship between data or nodes, it can support richer representations of data relationships. Als...
In the present paper, we study this problem for graphs containing no long claw, i.e. no induced subgraph obtained from the claw by subdividing each of its edges exactly once. To solve the problem in this class, we reduce it to the following question: given a graph $G$ and a subset ...
