自余弱弦图(On self-complementary weakly chordal graphs)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2010
The class of self-complementary (sc) weakly chordal graphs is studied, which is a generalization of self-complementary chordal graphs, lower and upper bounds for the number of two-pairs in sc weakly chordal graphs have been obtained.

Self-complementary and self-converse oriented graphs [PDF]

open access: yes, 1970
De Bruijn [I] applied his genoralization of PÓlya's fundamental theorem to provide an outline of a general method for enumerating self-complementary structures. This was used by Read [8] to carry out in detail the enumeration of self-complementary graphs

Independent Complementary Distance Pattern Uniform Graphs [PDF]

open access: yes, 2009
A graph G =(V,E) is called to be Smarandachely uniform k-graph for an integer k ≥ 1ifthereexistsM1,M2, ·· ·,Mk ⊂ V (G) such that fMi (u) ={d(u, v):v ∈ Mi} for ∀u ∈ V (G)−Mi is independent of the choice of u ∈ V (G)−Mi and integer i, 1 ≤ i ≤ k.

Homomorphisms and related contractions of graphs

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
For every homomorphism ϕ of a graph G there exists a contraction θϕ on G¯, the complement of G. Here we study the graph equation ϕ(G)=θϕ(G¯). In the course of our work we show that Hadwiger's Conjecture is true for every self-complementary graph.

Rough Neutrosophic Digraphs with Application

open access: yesAxioms, 2018
A rough neutrosophic set model is a hybrid model which deals with vagueness by using the lower and upper approximation spaces. In this research paper, we apply the concept of rough neutrosophic sets to graphs. We introduce rough neutrosophic digraphs and

Self-complementary (Pseudo-)Split Graphs

open access: yes, 2023
We are concerned with split graphs and pseudo-split graphs whose complements are isomorphic to themselves. These special subclasses of self-complementary graphs are actually the core of self-complementary graphs.

On self-graphoidal graphs and their complements

open access: yesKuwait Journal of Science
The graphoidal graph G of graph H is the graph obtained by taking graphoidal cover Ψ of H as vertices and two vertices are adjacent if and only if the corresponding paths have a non-empty intersection.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
