δ-Complement of a Graph

open access: yesMathematics, 2022
Let G(V,X) be a finite and simple graph of order n and size m. The complement of G, denoted by G¯, is the graph obtained by removing the lines of G and adding the lines that are not in G.

The existence of bipartite almost self-complementary 3-uniform hypergraphs [PDF]

open access: yesOpuscula Mathematica, 2023
An almost self-complementary 3-uniform hypergraph on \(n\) vertices exists if and only if \(n\) is congruent to 3 modulo 4 A hypergraph \(H\) with vertex set \(V\) and edge set \(E\) is called bipartite if \(V\) can be partitioned into two subsets \(V_1\

The Spectrum of Weighted Lexicographic Product on Self-Complementary Graphs

open access: yesIEEE Access, 2023
The lexicographic product, a powerful binary operation in graph theory, offers methods for creating a novel graph by establishing connections between each vertex of one graph and every vertex of another.

Generalized pairwise z-complementary codes [PDF]

open access: yes, 2008
An approach to generate generalized pairwise Z-complementary (GPZ) codes, which works in pairs in order to offer a zero correlation zone (ZCZ) in the vicinity of zero phase shift and fit extremely well in power efficient quadrature carrier modems, is ...

A Wide-Band Self-Complementary Tightly-Coupled Dipole Array With ±80° Scanning Range in the E Plane

open access: yesIEEE Access, 2020
When a magnetic current antenna is parallel to a metal ground, it can produce a nearly 180° 3dB beamwidth in the E plane, which can achieve a wide-angle scanning range in the E plane.

Complementary model of personality self-determination

open access: yesРоссийский психологический журнал, 2022
Introduction. The relevance of studying the phenomenon of self-determination is substantiated by the compliance of this research problem with two actively developing areas of personality psychology – the psychology of a change and the psychology of a ...

Correlations in totally symmetric self‐complementary plane partitions

open access: yesTransactions of the London Mathematical Society, 2021
Totally symmetric self‐complementary plane partitions (TSSCPPs) are boxed plane partitions with the maximum possible symmetry. We use the well‐known representation of TSSCPPs as a dimer model on a honeycomb graph enclosed in 1/12 of a hexagon with free ...
