On an Extremal Problem concerning Primitive Sequences
A sequence a,< . . . of integers is called primitive if no a divides any other . (a 1 < . . . will always denote a primitive sequence .) It is easy to see that if a i < . . . < a,,, < n then max k = [(n + 1) /2] . The following question seems to be very much more difficult . Put f(n) =niax E 1) , a,, where the maximum is taken over all primitive sequences all of wliose terms are not exceeding n...
متن کاملExtremal problems concerning Kneser graphs
Let d and S? be two intersecting families of k-subsets of an n-element set. It is proven that l~.JuS?l <(;:i)+(;::) holds for n>f(3+,/?)k, and equality holds only if there exist two points a, b such that {a, b} n F# 0 for all FE d u g, For n=2k+o(Jj;) an example showing that in this case max 1 d u B 1 = (1 o( 1 ))( ;) is given. This disproves an old conjecture of Erdiis [7]. In the second part ...
متن کاملAn Extremal Problem for Complete Bipartite Graphs
Define f(n, k) to be the largest integer q such that for every graph G of order n and size q, G contains every complete bipartite graph K u, ,, with a+h=n-k . We obtain (i) exact values for f(n, 0) and f(n, 1), (ii) upper and lower bounds for f(n, k) when ku2 is fixed and n is large, and (iii) an upper bound for f(n, lenl) .
متن کاملAn extremal problem for H-linked graphs
We introduce the notion of H-linked graphs, where H is a fixed multigraph with vertices w1; . . . ;wm. A graph G is H-linked if for every choice of vertices v1; . . . ; vm in G, there exists a subdivision of H in G such that vi is the branch vertex representing wi (for all i). This generalizes the notions of k -linked, k -connected, and k-ordered graphs. Given k and n 5k þ 6, we determine the l...
متن کاملEccentric Connectivity Index: Extremal Graphs and Values
Eccentric connectivity index has been found to have a low degeneracy and hence a significant potential of predicting biological activity of certain classes of chemical compounds. We present here explicit formulas for eccentric connectivity index of various families of graphs. We also show that the eccentric connectivity index grows at most polynomially with the number of vertices and determine ...
