Crewther's Relation in Different Schemes
Proceedings of 16th International Symposium on Radiative Corrections: Applications of Quantum Field Theory to Phenomenology — PoS(RADCOR2023), 2023 We examine Crewther's relation at high loop order in perturbative QCD and demonstrate how the relation is accommodated in gauge-parameter dependent schemes where the running of the gauge parameter has to be explicitly considered. Motivated by ensuring that the conformal properties of the relation are preserved at all the critical points of QCD ...

Stable difference scheme for a nonlocal boundary value heat conduction problem [PDF]
E-Journal of Analysis and Applied Mathematics, 2018 In this paper, a new finite difference method to solve nonlocal boundary value problems for the heat equation is proposed. The most important feature of these problems is the non-self-adjointness.

Construction of quaternary quantum error-correcting codes via orthogonal arrays
Frontiers in Physics, 2023 This paper presents a method based on orthogonal arrays of constructing pure quaternary quantum error-correcting codes. As an application of the method, some infinite classes of quantum error-correcting codes with distances 2, 3, and 4 can be obtained ...

On conjugate difference schemes: the midpoint scheme and the trapezoidal scheme
Discrete and Continuous Models and Applied Computational Science, 2021 The preservation of quadratic integrals on approximate solutions of autonomous systems of ordinary differential equations x=f(x), found by the trapezoidal scheme, is investigated. For this purpose, a relation has been established between the trapezoidal scheme and the midpoint scheme, which preserves all quadratic integrals of motion by virtue of ...

Mathematical modeling of the energy consumption problem
Қарағанды университетінің хабаршысы. Математика сериясы, 2022 The importance of energy-saving and correct design is obvious for energy efficiency. Correct design means that before construction considerable things, such as orientation or isolation decisions, need to be made. This study gives a mathematical model of
