Frucht’s Theorem for the Digraph Factorial
Discussiones Mathematicae Graph Theory, 2013 To every graph (or digraph) A, there is an associated automorphism group Aut(A). Frucht’s theorem asserts the converse association; that for any finite group G there is a graph (or digraph) A for which Aut(A) ∼= G.

Revisiting the Latin Vocabulary of Terminologia Histologica: II. Adjectives and Participles
Clinical Anatomy, EarlyView.ABSTRACT Terminologia Histologica, the international standard nomenclature of human histology and cytology, contains 1093 Latin words that appear to be used as adjectives. Among these, we identified 56 (5%) with a variety of linguistic issues, including typographical or spelling errors, less favored spelling variants, and several unfortunate word ...

On kernels by rainbow paths in arc-coloured digraphs
Open Mathematics, 2021 In 2018, Bai, Fujita and Zhang [Discrete Math. 341 (2018), no. 6, 1523–1533] introduced the concept of a kernel by rainbow paths (for short, RP-kernel) of an arc-coloured digraph DD, which is a subset SS of vertices of DD such that (aa) there exists no ...

Embedding b-Metric Spaces of Reducible Fuzzy Digraphs into Normed Spaces
Journal of Applied Science and EngineeringIn traditional and iterative algebraic techniques, representing fuzzy digraphs using their adjacency matrices can pose challenges, particularly when dealing with graphs featuring an extensive quantity of nodes or edges.

Extremal skew energy of digraphs with no even cycles [PDF]
Transactions on Combinatorics, 2014 Let $D$ be a digraph with skew-adjacency matrix $S(D)$. Then the skew energy of $D$ is defined to be the sum of the norms of all eigenvalues of $S(D)$. Denote by $mathcal{O}_n$ the class of digraphs on order $n$ with no even cycles, and by $mathcal{O ...

Rough Neutrosophic Digraphs with Application
Axioms, 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

On kernels in strongly game-perfect digraphs and a characterisation of weakly game-perfect digraphs
AKCE International Journal of Graphs and Combinatorics, 2020 We prove that the game-perfect digraphs defined by Andres (2012) with regard to a digraph version of the maker-breaker graph colouring game introduced by Bodlaender (1991) always have a kernel.
