A skew morphism of a finite group B is permutation φ that preserves the identity element and has property for every ∈ there exists positive integer ia such φ(ab) = φ(a)φia(b) all b B. The problem classifying morphisms cyclic groups notoriously hard, with no classification available up to date. Each Zn closely related specific Z|⟨φ⟩|, called quotient φ. In this paper, we use relationship other o...

In the Standard Model, the origin of CP-violation lies in the charged weak interaction sector, which involves transitions amongst quarks of different flavor and charge through the emission of a virtual W . The coupling strengths of these transitions for the 3 generations of quarks form a 3×3 matrix first introduced by M. Kobayashi and T. Maskawa and known as the (CKM) matrix. The CKM matrix is ...

We propose an experimental procedure to find out the medium modifications of the φ meson. The reaction is inclusive φ photoproduction in nuclei, looking for KK pairs from the φ decay with total momentum smaller than 100-150 MeV/c, which are made possible at energies of present laboratories from center of mass φ backward production and the help of Fermi motion. We have conducted a many body calc...

In this study, beginning and today expansion of universe are viewed in f(R,Φ,X) gravity. Field equations their solutions Friedmann-Lemaître-Robertson-Walker cosmologies with perfect fluid obtained by considering f(R,Φ,X)=f_0 R+f_1 X^q-V(Φ) model. Validity both gravity model for non-static space-time geometries is discussed making use the matter dynamics results such as pressure energy density. ...

A strong edge-coloring φ of a graph G assigns colors to edges such that φ(e1)≠φ(e2) whenever e1 and e2 are at distance no more than 1. It is equivalent proper vertex coloring the square line G. In 1990 Faudree, Schelp, Gyárfás, Tuza conjectured if bipartite with maximum degree 3 sufficiently large girth, then has most 5 colors. 2021 this conjecture was disproved by Lužar, Mačajová, Škoviera, So...
