Let D ∈ D(n,p) denote a simple random digraph obtained by choosing each of the (n choose 2) undirected edges independently with probability 2p and then orienting each chosen edge independently in one of the two directions with equal probability 1/2

We study the problem of efficiently sampling k-colorings of bipartite graphs. We show that a class of markov chains cannot be used as efficient samplers. Precisely, we show that, for any k, 6 ≤ k ≤ n {1/3-ε}, ε > 0 fixed, almost every bipartite

The chordality of a graph with at least one cycle is the length of the longest induced cycle in it. The odd (even) chordality is defined to be the length of the longest induced odd (even) cycle in it. Chordal graphs have chordality at most 3. We show

Fix positive integers k and l. Consider a random k-partite graph on n vertices obtained by partitioning the vertex set into V i, (i=1, …,k) each having size Ω(n) and choosing each possible edge with probability p. Consider any vertex x in any V i

We show that the intersection dimension of graphs with respect to several hereditary properties can be bounded as a function of the maximum degree. As an interesting special case, we show that the circular dimension of a graph with maximum degree Δ

We introduce and study an inductively defined analogue [Formula: see text] of any increasing graph invariant [Formula: see text]. An invariant [Formula: see text] is increasing if [Formula: see text] whenever [Formula: see text] is an induced subgrap

In this paper, we present an approximation algorithm for the maximum independent set (MIS) problem over the class of [Formula: see text]-VPG graphs when the input is specified by a [Formula: see text]-VPG representation. We obtain a [Formula: see tex
