Three-loop vertex integrals at symmetric point
Journal of High Energy Physics, 2021 This paper provides details of the massless three-loop three-point integrals calculation at the symmetric point. Our work aimed to extend known two-loop results for such integrals to the three-loop level.

Correlations at PT-Symmetric Quantum Critical Point. [PDF]
Physical Review Letters, 2021 We consider a PT-symmetric Fermi gas with an exceptional point, representing the critical point between PT-symmetric and symmetry broken phases. The low energy spectrum remains linear in momentum and is identical to that of a Hermitian Fermi gas.

Asymmetrical PZT applied to active reduction of asymmetrically vibrating beam – semi-analytical solution [PDF]
Archives of Acoustics, 2022 The article extended the idea of active vibration reduction of beams with symmetric modes to beams with asymmetric modes. In the case of symmetric modes, the symmetric PZT (s-PZT) was used, and the optimization of the problem led to the location of the s-

Nuclear Physics B, 2023 The ultraviolet completion is the Standard Model (SM) gauge-symmetric four-fermion couplings at the high-energy cutoff. Composite particles appear in the gauge symmetric phase in contrast with SM particles in the spontaneous symmetry-breaking phase.

Special exceptional point acting as Dirac point in one dimensional -symmetric photonic crystal
New Journal of Physics, 2022 We reveal that a special exceptional point (EP) can act as a Dirac point in a one-dimensional $\mathcal{P}\mathcal{T}$ -symmetric photonic crystal and prove it in detail using our extended first-principle theory.

On symmetry of the product of two higher-order quasi-differential operators
AIMS Mathematics, 2023 The symmetric realizations of the product of two higher-order quasi-differential expressions in Hilbert space are investigated. By means of the construction theory of symmetric operators, we characterize symmetric domains determined by two-point boundary

On coincidence and fixed-point theorems in fuzzy symmetric spaces [PDF]
Journal of Hyperstructures, 2012 In this paper, common fixed point theorems have been studied in fuzzy symmetric space instead of fuzzy metric space.Using weakly compatibility, property ( E.A.), we have generalized the common fixed point theorems for a pair of weakly compatible self ...

Mathematical Modelling and Analysis, 2021 The nonhomogeneous boundary value problem for the stationary NavierStokes equations in 2D symmetric multiply connected domain with a cusp point on the boundary is studied. It is assumed that there is a source or sink in the cusp point.

The Zero-Adjusted Log-Symmetric Distributions: Point and Intervalar Estimation [PDF]
Anais da Academia Brasileira de Ciências, 2023 In this paper, a new class of semi-continuous distributions called zero-adjusted log-symmetric is introduced and studied. Some properties and parameters estimation by maximum likelihood method are derived and confidence intervals (CIs) are developed.
