A note on self-complementary 4-uniform hypergraphs [PDF]

open access: yesOpuscula Mathematica, 2005
We prove that a permutation \(\theta\) is complementing permutation for a \(4\)-uniform hypergraph if and only if one of the following cases is satisfied: (i) the length of every cycle of \(\theta\) is a multiple of \(8\), (ii) \(\theta\) has \(1\), \(2\)

Self-complementary hypergraphs

open access: yes, 2010
In this thesis, we survey the current research into self-complementary hypergraphs, and present several new results. We characterize the cycle type of the permutations on n elements with order equal to a power of 2 which are k-complementing. The k-complementing permutations map the edges of a k-uniform hypergraph to the edges of its complement.

Self-complementary hypergraphs and their self-complementing permutations

open access: yesElectronic Notes in Discrete Mathematics, 2006
Abstract A k –uniform hypergraph H = ( V ; E ) is called self-complementary if there is a permutation σ : V → V , called self-complementing , such that for every k –subset e of V , e ∈ E if and only if σ ( e ) ∉ E . In other words, H is isomorphic with H ′ = ( V ; ( V k ) −

SPLHRNMTF: robust orthogonal non-negative matrix tri-factorization with self-paced learning and dual hypergraph regularization for predicting miRNA-disease associations [PDF]

open access: yesBMC Genomics
MicroRNAs (miRNAs) have been demonstrated to be closely related to human diseases. Studying the potential associations between miRNAs and diseases contributes to our understanding of disease pathogenic mechanisms.

Multi-Modal Enhancement Transformer Network for Skeleton-Based Human Interaction Recognition [PDF]

open access: yesBiomimetics
Skeleton-based human interaction recognition is a challenging task in the field of vision and image processing. Graph Convolutional Networks (GCNs) achieved remarkable performance by modeling the human skeleton as a topology.

Self-complementary hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2006
A k-uniform hypergraph H = (V;E) is called self-complementary if there is a permutation σ: V → V, called self-complementing, such that for every k-subset e of V, e ∈ E if and only if σ(e) / ∈ E. In other words, H is isomorphic with H ′ = (V;

Cyclic Partitions of Complete and Almost Complete Uniform Hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2022
We consider cyclic partitions of the complete k-uniform hypergraph on a finite set V, minus a set of s edges, s ≥ 0. An s-almost t-complementary k-hypergraph is a k-uniform hypergraph with vertex set V and edge set E for which there exists a permutation ...
