The stationary accretion of dark energy onto black holes is studied. General expressions are derived for the accretion rate of an ideal fluid with an arbitrary equation of state and for scalar fields. The black hole mass was found to decrease for the

The Israel equations for thin shells in General Relativity are derived directly from the least action principle. The method is elaborated for obtaining the equations for double layers in quadratic gravity from the least action principle.

The homogeneous and isotropic cosmological model in the Weyl conformal geometry is considered. We showed that, despite the conformal invariance, the dust matter is allowed in such a universe. It is shown that the number of dust particles is not conse

We investigated the possibility of the homogeneous and isotropic cosmological solution in Weyl geometry, which differs from the Riemannian geometry by adding the so called Weyl vector. The Weyl gravity is obtained by constructing the gravitational La

The paper focuses on the technology of producing ZrO2-Y2O3 ceramic fibers by impregnating twisted viscose yarns with zirconyl nitrate solutions with the addition of yttrium nitrate and subsequent heat treatment. We determined the effect of the impreg
