چکیده

A bicolorable STS(v) is a Steiner triple system whose vertices are colored in such way that every block receives precisely two colors. A k-bicoloring of a STS is a vertex coloring using each of k colors, and the feasible set Ω is a set of integers k for which k-bicolorings exist. In this paper, we study feasible sets of STS(v)s of all orders v < 50.

Path-Bicolorable Graphs

In this paper, we introduce the notion of path-bicolorability that generalizes bipartite graphs in a natural way: For k ≥ 2, a graph G = (V,E) is Pk-bicolorable if its vertex set V can be partitioned into two subsets (i.e., colors) V1 and V2 such that for every induced Pk (i.e., path with exactly k − 1 edges and k vertices) in G, the two colors alternate along the Pk, i.e., no two consecutive v...

Recognizing Chordal Probe Graphs and Cycle-Bicolorable Graphs

A graph G = (V,E) is a chordal probe graph if its vertices can be partitioned into two sets, P (probes) and N (non-probes), where N is a stable set and such that G can be extended to a chordal graph by adding edges between non-probes. We give several characterizations of chordal probe graphs, first, in the case of a fixed given partition of the vertices into probes and non-probes, and second, i...

Streptococcal Toxic Shock Syndrome Caused by Group G Streptococcus, United Kingdom

We describe successful management of 3 patients with streptococcal toxic shock syndrome (STSS) attributable to group G Streptococcus infection. This small series supports recognition of group G Streptococcus in the etiology of STSS. We propose intravenous immunoglobulin be used in treatment as it is for STSS caused by group A Streptococcus.

Purification of large bicolorable graph states

We describe purification protocols for bicolorable graph states. The protocols scale efficiently for large graph states. We introduce a method of analysis that allows us to derive simple recursion relations characterizing their behavior as well as analytical expressions for their thresholds and fixed-point behavior. We introduce two purification protocols with high threshold. They can, for grap...
