A plane symmetric cosmological model with perfect fluid has been studied in general theory of relativity. The general solutions of the corresponding Einstein's field equations have been obtained with ...

In this paper, we analysed the five-dimensional plane-symmetric cosmological model containing perfect fluid in the context of f (R, T) gravity. Field equations have solved for two class of f (R, T) ...

Annals of Mathematics, SECOND SERIES, Vol. 181, No. 2 (March, 2015), pp. 769-807 (39 pages) We study the nonhomogeneous boundary value problem for the Navier-Stokes equations of steady motion of a ...

1. Introduction The problem of a hyperboloid being intersected by a plane is described in Section 1. The means to treat the problem are provided in Sections 2, 3 and 4. In the end of Section 4 first ...

We consider the problem of motion of a rotationally symmetric ellipsoid on a fixed perfectly rough plane. Using the Kovacic algorithm we found several cases when equations of motion of the ellipsoid ...

The symmetric ortho-symmetric maximal and minimal rank solutions to a class of matrix equation and their optimal approximation are considered. By applying the matrix rank method, the necessary and ...

Eqs. 1.2 are an extension of Maxwell’s equations where the normal zero on the right hand side of Eq. 1.2c has been replaced with a “missing” magnetic charge density ρm ρ m term, making it more ...

These matrices (C, P, T) have like the Dirac matrices the dimension 8 × 8 and still need to be determined by explicit operation of C,P,T C, P, T on the Dirac equation. The transformed fields are ...

In this note, the ideas employed in [1] to treat the problem of an ellipsoid intersected by a plane are applied to the analogous problem of a hyperboloid being intersected by a plane. The curves of ...
