Generalized Turán problems for $K_{2,t}$

چکیده
The generalized Turán function $\mathrm{ex}(n,H,F)$ denotes the largest number of copies $H$ among $F$-free $n$-vertex graphs. We study when or $F$ is $K_{2,t}$. determine order magnitude $\mathrm{ex}(n,H,K_{2,t})$ a tree, and its asymptotics for large class trees. also $\mathrm{ex}(n,K_{2,t},F)$ has chromatic at least three bipartite with one part most two.

A hypergraph regularity method for generalized Turán problems
Wedescribe amethod that we believemay be foundational for a comprehensive theory of generalized Turán problems. The cornerstone of our approach is a quasirandom counting lemma for quasirandom hypergraphs, which extends the standard counting lemma by not only counting copies of a particular configuration but also showing that these copies are evenly distributed.We demonstrate the power of the me...
متن کاملSupersaturation For Ramsey-Turán Problems
For an l-graph G, the Turán number ex(n,G) is the maximum number of edges in an n-vertex l-graph H containing no copy of G. The limit π(G) = limn→∞ ex (n,G)/ ( n l ) is known to exist [8]. The Ramsey-Turán density ρ(G) is defined similarly to π(G) except that we restrict to only those H with independence number o(n). A result of Erdős and Sós [3] states that π(G) = ρ(G) as long as for every edg...
متن کاملTurán Problems for Bipartite Graphs ∗
We consider an infinite version of the bipartite Turán problem. Let G be an infinite graph with V (G) = N, and let Gn be the n-vertex subgraph of G induced by the vertices {1, 2, . . . , n}. We show that if G is K2,t+1-free, then for infinitely many n, e(Gn) ≤ 0.471 √ tn3/2. Using the K2,t+1-free graphs constructed by Füredi, we construct an infinite K2,t+1-free graph with e(Gn) ≥ 0.23 √ tn3/2 ...
متن کاملRainbow Turán Problems
For a fixed graph H, we define the rainbow Turán number ex∗(n,H) to be the maximum number of edges in a graph on n vertices that has a proper edge-colouring with no rainbow H. Recall that the (ordinary) Turán number ex(n,H) is the maximum number of edges in a graph on n vertices that does not contain a copy of H. For any non-bipartite H we show that ex∗(n,H) = (1+o(1))ex(n,H), and if H is colou...
متن کاملTurán problems for integer-weighted graphs
A multigraph is (k, r)-dense if every k-set spans at most r edges. What is the maximum number of edges exN(n, k, r) in a (k, r)-dense multigraph on n vertices? We determine the maximum possible weight of such graphs for almost all k and r (e.g., for all r > k) by determining a constant m = m(k, r) and showing that exN(n, k, r) = m ( n 2 ) +O(n), thus giving a generalization of Turán’s theorem. ...
