A characterization of soluble groups in which normality is a transitive relation [PDF]
International Journal of Group Theory, 2017 A subgroup $X$ of a group $G$ is said to be an H-subgroup if NG(X) ∩ Xg ≤ X for each element $g$ belonging to $G$. In [M. Bianchi and e.a., On finite soluble groups in which normality is a transitive relation, J.

Some characterisations of groups in which normality is a transitive relation by means of subgroup embedding properties [PDF]
International Journal of Group Theory, 2018 In this survey we highlight the relations between some subgroup embedding properties that characterise groups in which normality is a transitive relation in certain universes of groups with some finiteness properties.

A 2-arc Transitive Hexavalent Nonnormal Cayley Graph on A119
Mathematics, 2021 A Cayley graph Γ=Cay(G,S) is said to be normal if the base group G is normal in AutΓ. The concept of the normality of Cayley graphs was first proposed by M.Y.

RUDN Journal of Economics, 2023 The reserch explores multiple approaches to the term “new normality”, which appeared in the scientific economic community after the 2008 crisis, and became relevant again with the proclamation of a “new economic era” in China, the “entry” of the world ...

On non-normal cyclic subgroups of prime order or order 4 of finite groups
Open Mathematics, 2021 In this paper, we call a finite group GG an NLMNLM-group (NCMNCM-group, respectively) if every non-normal cyclic subgroup of prime order or order 4 (prime power order, respectively) in GG is contained in a non-normal maximal subgroup of GG.

Study of the Superconducting to Normal Transition [PDF]
Journal of Superconductivity and Novel Magnetism, 2019 A model, based on classical mechanics and thermodynamics and valid for \textit{all} superconductors, is devised to investigate the properties of the \textit{current-driven}, superconducting to normal transition. This process is shown to be reversible. An original derivation of the BCS variational procedure is given.

Normal stresses at the gelation transition [PDF]
Physical Review E, 2002 A simple Rouse-type model, generalised to incorporate the effects of chemical crosslinks, is used to obtain a theoretical prediction for the critical behaviour of the normal-stress coefficients $Ψ_{1}$ and $Ψ_{2}$ at the gelation transition. While the exact calculation shows $Ψ_{2}\equiv 0$, a typical result for these types of models, an additional ...

Instantaneous Normal Modes and the Glass Transition [PDF]
Physical Review Letters, 1995 The "instantaneous" normal mode (INM) spectrum for a model soft-sphere system is calculated via molecular-dynamics computer simulation for a variety of temperatures both above and below the observed glass transition temperature. In such spectra, the modes can be classified as either real or imaginary frequency.

Polaritonic normal modes in transition state theory [PDF]
The Journal of Chemical Physics, 2020 A series of experiments demonstrates that strong light–matter coupling between vibrational excitations in isotropic solutions of molecules and resonant infrared optical microcavity modes leads to modified thermally activated kinetics. However, Galego et al. [Phys. Rev.
