Exponentially-fitted Third-Order Adams-Bashfort Method Paper ID: AJMPA-11-10-2019-135
Abstract : In this paper, the construction of Exponentially-Fitted (EF) versions of the third-order Adam-Bashfort method for oscillatory problems is presented. The convergence and stability properties of the constructed methods are investigated. Numerical experiments confirming the theoretical expectations regarding the constructed methods compared with other standard classical methods are also presented.

Turbulence birth from Poiseuille flow curvature Paper ID: AJMPA-11-10-2019-134
Abstract : In this paper, we considered the well-known parabolic velocity field of Poiseuille flow, as a Riemannian manifold. Calculations of both first and second fundamental forms allowed mean and Gauss curvatures of the paraboloid of revolution, to be calculated. From the Lamb form of Navier-Stokes equation, we calculated both the flexion product and enstrophy giving the Lamb vector divergence as a function of Gauss curvature of the laminar velocity field. These results allowed the stability of Poiseuille flow to be investigated through the influence of maximum flow curvature and the Lamb vector divergence. We showed that classical critical Reynolds number approach is not enough to explain the change from laminar to transition flow regime. A new method, based on Gauss curvature calculation of the Riemannian manifold is then proposed.

Free Semi-Group Introductions Paper ID: AJMPA-01-10-2019-127
Abstract : Let and be without two semi-groups. We characterize outside direct result of two free semi-groups as an arranged pair of words with the end goal that and. We explore the introductions of the outer direct result of free semi-groups, state and demonstrate under certain conditions that the outer direct result of two limited created free semi-groups is limited produced, likewise the outside direct result of two limited exhibited free semi-groups is limitedly introduced

The connection of physical fields with material media: The nature and origins of dark matter and dark Energy Paper ID: AJMPA-27-09-2019-110
Abstract : Investigation of the mathematical physics equations, which describe material media such as thermodynamic, gas-dynamic and cosmic and other media, shows that they possess hidden invariant properties. Such properties correspond to that of field theory equations, which describe physical fields. This discloses a mechanism of physical fields generation by material media. Such specific properties of mathematical physics equations are connected with conservation laws. They are described by skew-symmetric differential forms which properties correspond to conservation laws.

The computation of the Kadić-Edelen forces using the principle of least action. Paper ID: AJMPA-24-08-2019-106
Abstract : In this paper, basing on the principle of least action, we calculate the forces which act on the momentum of a particle in a tensor interaction field. These forces were obtained by Kadić-Edelen within the framework of the continuum dislocation theory in analogy with electrodynamics. It is shown that: 1) the centrally symmetric force of the tensor interaction field is similar to the Coulomb force. It contains a potential term of the Euler hydrodynamics equations and is responsible for the homogeneous motions of the continuous medium; 2) the vortex force of the tensor field is similar to the Lorentz force. It coincides with the force of Peach-Koehler, in a solid state, and is responsible for the vortex motion of the continuous medium. It is concluded that the forces obtained act in any medium, and not only in a solid state, as was previously stated in the theory of Kadić-Edelen.
