Pournin showed in [23] that the diameter of T n is 2n− 10 for n > 12. We show connectedness of D n and a linear diameter bound for D n by first showing corresponding statements for T

WebInduced Ramsey-type theorems Jacob Fox⁄ Benny Sudakovy Abstract We present a unifled approach to proving Ramsey-type theorems for graphs with a forbidden induced subgraph which can be used to extend and improve the earlier results of R˜odl, Erd}os-Hajnal, Pr˜omel-R˜odl, Nikiforov, Chung-Graham, and Luczak-R˜ˆ odl. The proofs are … Webinduced subgraphs, smaller graphs obtained by selecting a subset of the vertices and using all edges with both endpoints in that subset, homeomorphic subgraphs (also called topological minors ), smaller graphs obtained from subgraphs by collapsing paths of degree-two vertices to single edges, or
WebIf r − δ > 0 then create two disjoint copies of G, say G 1 and G 2. For any vertex v in G of degree less than r, add an edge between the corresponding vertices v 1 in G 1, v 2 in G 2. Call the resulting graph G ′. Then G ′ contains G as an induced subgraph, and r − δ ( G ′) = r − δ ( G) − 1. You can construct the graph ... WebNotice that every induced subgraph is also an ordinary subgraph, but not conversely. Think of a subgraph as the result of deleting some vertices and edges from the larger graph. For the subgraph to be an induced subgraph, we can still delete vertices, but now we only delete those edges that included the deleted vertices. Example 4.1.4.
Web3 induced subgraph. This is a contradiction, and thus any graph with an odd cycle must have either P 4 or C 3 as an induced subgraph. This completes the proof. (Note: The word \induced" is very important here! See the de nition of \induced subgraph" in the lecture notes it is not the same as a \subgraph".) (b)Assume in addition that G is ... WebDense subgraph mining. A series of studies have utilized dense subgraph mining to detect fraud, spam, or communities on social net-works and review networks [19, 28, 29]. However, they are proposed for static graphs. Some variants [2, 13] are designed to detect dense subgraphs in dynamic graphs. [30] is proposed to spot generally dense
