Fuglede's conjecture holds on cyclic groups $\mathbb{Z}_{pqr}$

open access: yesDiscrete Analysis, 2019
Fuglede's conjecture holds on cyclic groups $\mathbb{Z}_{pqr}$, Discrete Analysis 2019:14, 14 pp. A conjecture of Fuglede from 1974 states that a measurable set $E\subset \mathbb R^n$ of positive Lebesgue measure has a set of translates that tile ...

Open Set Lattices of Subspaces of Spectrum Spaces

open access: yesDemonstratio Mathematica, 2015
We take a unified approach to study the open set lattices of various subspaces of the spectrum of a multiplicative lattice L. The main aim is to establish the order isomorphism between the open set lattice of the respective subspace and a sub-poset of L.

QCD sum rule studies of $$s s {\bar{s}} {\bar{s}}$$ sss¯s¯ tetraquark states with $$J^{PC} = 1^{+-}$$ JPC=1+-

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We apply the method of QCD sum rules to study the structure X newly observed by the BESIII Collaboration in the $$\phi \eta ^\prime $$ ϕη′ mass spectrum in 2.0–2.1 GeV region in the $$J/\psi \rightarrow \phi \eta \eta ^\prime $$ J/ψ→ϕηη′ decay.

L-Prime Spectrum of Modules

open access: yes, 2009
We investigate the Zariski Topology on the L-prime spectrum of modules consisting of the collection of all prime L-submodules and prove some useful results.

On Nilcompactifications of Prime Spectra of Commutative Rings

open access: yes, 2015
Given a ring R and S one of its ideals, we obtain a compactification of the prime spectrum of S through a mainly algebraic process. We name it the R-nilcompactification of SpecS. We study some categorical properties of this construction.Comment: 12 pages,

Splitting Madsen-Tillmann spectra II. The Steinberg idempotents and Whitehead conjecture

open access: yes, 2015
We show that, at the prime $p=2$, the spectrum $\Sigma^{-n}D(n)$ splits off the Madsen-Tillmann spectrum $MTO(n)=BO(n)^{-\gamma_n}$ which is compatible with the classic splitting of $M(n)$ off $BO(n)_+$.

Oscillatory States of Impurity Micro-formations on the Hexagonal Substrate [PDF]

open access: yesЖурнал нано- та електронної фізики, 2015
It is shown that the set of oscillatory frequencies directly indicates the form of formation and the number of atoms in the bunch. With regard to the chain-like formations, it is found that the spectrum of the object, wherein the number of atoms is prime

Superconductivity of bad fermions and the origin of two gaps in cuprates

open access: yesCommunications Physics
The spectral properties of the doped t–t’ Hubbard model, using parameters typical for high-temperature cuprate superconductors, and the mechanism of d-wave pairing remain among the longstanding problems of many-body fermionic materials.
