The LTB model is studied as the Caushy problem for the equations defined two metrical functions λ(μ, τ) and ω(μ, τ). The initial conditions throught metrical functions are presented. The rules of calculating three undetermined functions f(μ), F (μ) and F(μ) are obtained. The general expressions for the density and Habble function in the LTB model are written by the metrical functions. PACS numb...

We show that instantons violate a supersymmetric identity in a classically supersymmetric Higgs model with no massless fermions. This anomalous breaking arises because the correct perturbative expansion in the instanton sector is not supersymmetric. The attempt to construct a manifestly supersymmetric expansion generates infra-red divergences.

A method for calculating the relativistic path integral solution via sum over perturbation series is given. As an application the exact path integral solution of the relativistic Aharonov-Bohm-Coulomb system is obtained by the method. Different from the earlier treatment based on the space-time transformation and infinite multiple-valued trasformation of Kustaanheimo-Stiefel in order to perform...

Multidimensional gravitational model containing several dilatonic scalar fields and antisymmetric forms is considered. The manifold is chosen in the form M = M 0 × M 1 ×. .. × M n , where M i are Einstein spaces (i ≥ 1). When metric is block-diagonal, all fields and scale factors of the metric depend (essentially) on the point of M 0 and for the forms composite (electromagnetic) p-brane Ansatz ...
