## Let be a distance-regular graph with where r β₯ 2 and c r +1 > 1. We prove that r = 2 except for the case a 1 = a r +1 = 0 and c r +1 = 2 by showing the existence of strongly closed subgraphs.

## Abstract For a graphb __F__ without isolated vertices, let __M__(__F__; __n__) denote the minimum number of monochromatic copies of __F__ in any 2βcoloring of the edges of __K__~__n__~. Burr and Rosta conjectured that when __F__ has order __t__, size __u__, and __a__ automorphisms. Independent
Various Hamiltonian-like properties are investigated in the squares of connected graphs free of some set of forbidden subgraphs. The star K,+ the subdivision graph of &, and the subdivision graph of K1,3 minus an endvertex play central roles. In particular, we show that connected graphs free of the
Let \_(n, m, k) be the largest number \_ # [0, 1] such that any graph on n vertices with independence number at most m has a subgraph on k vertices with at lest \_ } ( k 2 ) edges. Up to a constant multiplicative factor, we determine \_(n, m, k) for all n, m, k. For log n m=k n, our result gives \_(
