چکیده
We obtain and study static, spherically symmetric solutions for the Einstein — generalized Maxwell field system in 2n dimensions, with possible inclusion of a massless scalar field. The generalization preserves the conformal invariance of the Maxwell field in higher dimensions. Almost all solutions exhibit naked singularities, but there are some classes of black hole solutions. For these cases the Hawking temperature is found and its charge/mass and dimension dependence is discussed. It is shown that, unlike the previously known multidimensional black hole solutions, in our case the black hole temperature may infinitely grow in the extreme case (that of minimum mass for given charges).

The problems causality and causality violation in topologically nontrivial spacetime models are considered. To this end the mixed boundary problem for traversable wormhole models is formulated and the influence of the boundary conditions on the causal properties of space-time is analyzed

The so called ”Principle of the self-consistency” for space-time models with causality violation, which was firstly formulated by I.D.Novikov, is discussed for the test particle motion and for test scalar field. It is shown that the constraints, which provide the self-concistensy of test particle motion have pure geometrical (topological) nature. So, the recent statement that ”The Principle of ...

The problem of topology change description in gravitation theory is analized in detailes. It is pointed out that in standard four-dimensional theories the topology of space may be considered as a particular case of boundary conditions (or constraints). Therefore, the possible changes of space topology in (3+1)-dimensions do not admit dynamical description nor in classical nor in quantum theorie...

A multidimensional gravitational model on the manifold M = M0 × ∏ n i=1 Mi , where Mi are Einstein spaces (i ≥ 1), is studied. For N0 = dimM0 > 2 the σ model representation is considered and it is shown that the corresponding Euclidean Toda-like system does not satisfy the Adler-van-Moerbeke criterion. For M0 = R N0 , N0 = 3, 4, 6 (and the total dimension D = dimM = 11, 10, 11, respectively) no...
