[en] A theory of gravitation is proposed which exhibits the property of saturation of the gravitational forces at small distances

[en] On the basis of the simplest supergravity group we develop the formalism of differential geometry. In this formalism all geometric objects, such as supertetrads (supervierbeins), connections, etc. are expressed in terms of the axial-vector gravitational superfield

[en] It is considered the problem of motion of two viscoelastic bodies in the gravitational field of MMP. Earlier we found the displacements of points of bodies caused by the action of centrifugal, elastic and dissipative forces. In this paper we calculated analytically three PP using these displacements for centrifugal, elastic and dissipative forces. These three types of displacements change accordingly the shape of the body. And PP is due to the difference between the shape of deformable bodies and balls. Knowing the PP we can find the torques, which determine the rotational motion of the body. As an example, we have calculated the shape of the body caused by elastic displacements and the torques acting on the body. (paper)

[en] The fermion-graviton system at linearized level in a (2+1)-dimensional space-time with the gravitational Chern-Simons term is studied. In this approximation it is shown that this system presents anomalous rotational properties and spin, in analogy with the gauge field-matter system. (A.C.A.S.)

[en] Einstein's theory of gravitation is a geometrical theory, it can however be considered as a gauge theory of the Lorentz group as well. It seems, therefore, to be worthwhile to exhibit the essential geometrical concepts which allow a formulation of gauge theories, of Einstein's gravitational theory, of supergauge theories and of supergravity as well. This common concepts are manifolds, tensor fields, differential forms, exterior derivatives, connection, covariant derivatives, torsion and curvature

[en] Using our spinorial approach, a quantization method for the gravitational field is given. The wave formalism gives Einstein equations if there exists harmonic adapted coordinates for some parallelization of the space-time

[en] The minute yet effective impact of gravitational potential in the central region of a long tube magnetic container of non-neutral plasmas can be utilized for the measurement of the gravitational acceleration of antimatter particles. The slight change in distribution of plasma particles along the gravitational field affects the internal electric field of the plasma, which in turn affects the frequency of the magnetron motion of its particles. Thus, a rather straightforward relation is established between the gravitational acceleration of the particles and their magnetron frequencies, which is measurable directly, determining the value of the gravitational acceleration.
