چکیده
For the closed relativistic string carrying a pointlike mass the exact solutions of the dynamical equations are obtained and studied. These solutions describe states of the mentioned system moving in Minkowski space and also in the space that is the direct product of Minkowski space and a compact manifold (torus). We consider the closed relativistic string with one massive point (homeomorphic to a circle with a marked point) moving in the space M = R × K. Here R is 3 + 1 dimensional Minkowski space and K is a compact manifold with D − 4 dimensions resulting from the compactification procedure of the string theory [1]. The action for the considered system is S = −γ ∫

The double torus provides a relativistic model for a closed 2D cosmos with topology of genus 2 and constant negative curvature. Its unfolding into an octagon extends to an octagonal tesselation of its universal covering, the hyperbolic space H. The tesselation is analysed with tools from hyperbolic crystallography. Actions on H of groups/subgroups are identified for SU(1, 1), for a hyperbolic C...

A global phase time is identified for homogeneous and isotropic cosmological models yielding from the low energy effective action of closed bosonic string theory. When the Hamiltonian constraint allows for the existence of an intrinsic time, the quantum transition amplitude is obtained by means of the usual path integral procedure for gauge systems.

We consider the relativistic quantum mechanics of a two interacting fermions system. We first present a covariant formulation of the kinematics of the problem and give a short outline of the classical results. We then quantize the system with a general interaction potential and deduce the explicit equations in a spherical basis. The case of the Coulomb interaction is studied in detail by numeri...

Despite of still bothering uncertainties and ongoing controversy, the convectively supported neutrino-heating mechanism (1) must be considered as a promising way to explain supernova explosions of massive stars. Neutrinos drive the evolution of the collapsing stellar core and of the forming neutron star and dominate the event energetically by carrying away about 99% of the gravitational binding...
