Bipartite Ramsey numbers involving stars, stripes and trees
The Ramsey number R(m, n) is the smallest integer p such that any blue-red colouring of the edges of the complete graph Kp forces the appearance of a blue Km or a red Kn.

This paper deals with bithreshold graphs and their characterization. After having given some necessary properties the authors succeed in proving a complete characterization of the class of bipartite bithreshold graphs by means of 11 not bithreshold (so-called forbidden induced subgraphs) and 5 classes of induced subgraphs.

Decomposition of complete graphs into small graphs [PDF]
In 1967, A. Rosa proved that if a bipartite graph \(G\) with \(n\) edges has an \(\alpha\)-labeling, then for any positive integer \(p\) the complete graph \(K_{2np+1}\) can be cyclically decomposed into copies of \(G\).

Detecting and generating overlapping nested communities
Nestedness has been observed in a variety of networks but has been primarily viewed in the context of bipartite networks. Numerous metrics quantify nestedness and some clustering methods identify fully nested parts of graphs, but all with similar ...

Dynamic Load Balancing Algorithm Based on Optimal Matching of Weighted Bipartite Graph
When the server cluster is processing concurrent task requests, if the performance difference among servers is not fully considered, task allocation will be unreasonable, which will lead to an increase in task making span and a decrease in cluster ...

Bipartite powers of k-chordal graphs [PDF]
Let k be an integer and k \geq 3. A graph G is k-chordal if G does not have an induced cycle of length greater than k. From the definition it is clear that 3-chordal graphs are precisely the class of chordal graphs. Duchet proved that, for every positive

Antifactors of regular bipartite graphs [PDF]
Let $G=(X,Y;E)$ be a bipartite graph, where $X$ and $Y$ are color classes and $E$ is the set of edges of $G$. Lov\'asz and Plummer \cite{LoPl86} asked whether one can decide in polynomial time that a given bipartite graph $G=(X,Y; E)$ admits a 1-anti ...

Consider two bipartite graphs \(G=\{L,R,E\}\) and \(G'=\{L',R',E'\}\). A bijection \(f:L\cup R\to L'\cup R'\) such that \(f(L)=L'\) and \(f(u)f(v)\not\in E'\) for every edge \(uv\in E\) is called a bi-placement of \(G\) and \(G'\). The graphs \(G\) and \(G'\) are called bi-placeable if there exists a bi-placement of \(G\) and \(G'\).
