Star-path and star-stripe bipartite Ramsey numbers in multicoloring [PDF]
For given bipartite graphs G 1 ,G 2 ,…,G t , the bipartite Ramsey number bR(G 1 ,G 2 ,…,G t ) is the smallest integer n such that if the edges of the complete bipartite graph K n,n are partitioned into t disjoint color classes giving t ...

On interval number in cycle convexity [PDF]
Recently, Araujo et al. [Manuscript in preparation, 2017] introduced the notion of Cycle Convexity of graphs. In their seminal work, they studied the graph convexity parameter called hull number for this new graph convexity they proposed, and they ...

A Constructive Extension of the Characterization on Potentially Ks,t-Bigraphic Pairs
Let Ks,t be the complete bipartite graph with partite sets of size s and t. Let L1 = ([a1, b1], . . . , [am, bm]) and L2 = ([c1, d1], . . . , [cn, dn]) be two sequences of intervals consisting of nonnegative integers with a1 ≥ a2 ≥ . . . ≥ am and c1 ≥ c2

A heuristic method for bi-decomposition of partial Boolean functions
The problem of decomposition of a Boolean function is to represent a given Boolean function in the form of a superposition of some Boolean functions whose number of arguments are less than the number of given function.

Solutions to problems about potentially Ks,t-bigraphic pair
Let S=(a1,…,am;b1,…,bn)S=\left({a}_{1},\ldots ,{a}_{m};\hspace{0.33em}{b}_{1},\ldots ,{b}_{n}), where a1,…,am{a}_{1},\ldots ,{a}_{m} and b1,…,bn{b}_{1},\ldots ,{b}_{n} are two nonincreasing sequences of nonnegative integers. The pair S=(a1,…,am;b1,…,bn)S=

Complete subgraphs of bipartite graphs and applications to trace languages [PDF]
Summary: Motivated by a concurrency problem, a lattice describing a certain concurrent behaviour is constructed, whose elements are complete subgraphs of a bipartite graph. As an application of this construction, one derives, extending a result of Cori and Perrin, an explicit computation for the product of trace languages.

Random multilinear maps and the Erdős box problem
Random multilinear maps and the Erdős box problem, Discrete Analysis 2021:17, 8 pp. A major theme in extremal combinatorics is determining the maximum number of edges that a graph or hypergraph can have if it does not contain a certain fixed graph or ...

Optimal orientations of subgraphs of complete bipartite graphs
Summary: For a graph \(G\), let \(\mathcal{D}(G)\) be the set of all strong digraphs \(D\) obtained by the orientations of \(G\). The orientation number of \(G\) is \(\vec{d}(G)=\min \{d(D)\mid D\in \mathcal{D}(G)\}\), where \(d(D)\) denotes the diameter of the digraph \(D\).
